Enclave Department of the Army

Duty, honor, courage, Semper Fidelis (Horrigan's last words)

Main article: Enclave

Overview
According to Fallout Bible the Enclave army was composed of hundreds of soldiers armed with advanced versions of Power Armor and guns, that rival the Brotherhood of Steel.
 * It seems the Enclave army consisted of 200-900 soldiers (which is comparable to contemporary US Army battalion with 300 – 1000 soldiers). According to dr. Charles Curling there were thousand inhabitants on the oil rig.
 * Company was probably the highest grade unit organization (the only example - Enclave Control Company). It is not certain how much crews had the Enclave company, however the smallest contemporary US Army company consists of 62 crews.
 * 83 Enclave troops can be encountered on the accessible levels of the oil rig and 30 – at the Camp Navarro, which is faction of 13-57% total Enclave soldiers.

Recruitment

 * External (local) recruitment for lower posts at understaffed Camp Navarro was possible. Its known possible reasons were desertions and the Enclave dwellers antipathy for the mainland. There were no reconditioning procedures or facilities. Possibly such recruits never visited the oil rig (it was no problem when Chosen One didn't know where the oil rig is). According to one of Navarro technicians some subversives (external recruits probably) were not entitled and not able to pilot vertibirds.
 * Volontaire recruitment on the oil rig for technician positions at Camp Navarro was possible.
 * In the Enclave armed forces recruited significant number of women - eg. some guards served at Camp Navarro or were vertibird crew during New Reno flights.

Known ranks in the Enclave

 * Troop, Soldier, Guard, Private; Guards at Camp Navarro were called Soldiers by senior staff,
 * Private First Class - described as pfc-tech, grade X, a soldier in a duty uniform (found at Navarro dialogue files: Cctech.msg)
 * Sergeant, the only appearing NCO position, eg.:
 * Sgt. Bracks - in charge at the Enclave Patrolmen checkpoint 3, destroyed in Mariposa Military Base,
 * Sgt. Dornan - drill Sergeant at Camp Navarro, the only sergeant there (reffered just as a "Sarge" by other personnel), had some insignia on the breastplate (like other military personnel there),
 * Sgt. Granite - leader of the Enclave Control Company squad, had Sergeant's chevrons on his shoulder,
 * on the oil rig: guards were floating "nothing to report Sarge", Curling was going to complain to some Sergeant,
 * Captain, eg. Cap. Pickard, in charge at the Enclave Patrolmen checkpoint 1, destroyed in Mariposa Military Base; the highest rank known the Enclave Patrolman (notice: in the contemporary US Army a Captain typically commands company-size unit, 62 to 190 soldiers),
 * Lieutenant Colonel, eg. Lt. Col. dr. Charles Curling, United States Chemical Corps head, reporting to the Cabinet (notice: in the contemporary US Army a Lieutenant Colonel typically commands a battalion-sized unit, 300 to 1000 soldiers),
 * Colonel, eg. Col. Sanders, CO for Mariposa Military Base excavation, the highest rank known officer, the highest rank known officer present on the field also, subordinated to the CHQ then (notice: in the contemporary US Army a Colonel typically commands brigade-sized units, 3000 to 5000 soldiers).

Undefined ranks Enclave military staff
There are also 2 positions at Camp Navarro with undefined rank:
 * the Base Commander, the superior officer there, a long-serving soldier (refered as "old man" by his door guard, but described as "she" by the game engine); at least Base Commander should have the lowest officer's rank at the Enclave armed forces; under his command was 39 crew outpost, which was not only an ordinary platoon equivalent, but independent unit on the main land also (notice: (1) in contemporary US Army the lowest officers grade is Second Lieutenant, that usually commanding platoon size units; (2) the lowest known officers grade in the Enclave armed forces was Captain; (3) Camp Navarro Base Commander responsibility was greater then ordinary platoon leader),
 * the Quartermaster.

Known pre-war US Armed Forces ranks
The Enclave of the United States of America was legal continuation of the pre-war USA. Known pre-war US Armed Forces ranks were also:
 * Private, eg. Private Dobbs and Private Callow, stored at the Sierra Army Depot,
 * Corporal, eg. Corp. Dixon, serving at the Sierra Army Depot, or Corp. Armstrong of the Great Midwest Commonwealth 4th or 13th Armored Infantry Division (van Buren demo character),
 * Sergeant, eg. Sgt. Platner, serving at the Mariposa Military Base in 2077 and Sgt. Dennis Allen (in year 2134, 57 years after the War, Brotherhood of Steel member in fact),
 * Captain, eg. Cap. Roger Maxson, serial number 072389, serving at the Mariposa Military Base in 2077 as security guard (MP) there, an active commanding officer there following the untimely death of Colonel Robert Spindel,
 * Major, eg. Maj. Barnett, serving at the West Tech facility,
 * Colonel, eg. Col. Robert Spindel, in charge at the Mariposa Military Base, or Col. Green, the head of security and operations at the Los Alamos Nuclear Testing Facility (experience level 15 as a ghoul, van Buren character),
 * General, eg. Gen. Clifton, in charge at the Sierra Army Depot in 2077.

The NCR army ranks
According to one of Fallout 2 endings shaken by the assassination of Vice-President Carlson, right-wing elements seize control of the Congress and set the New California Republic on the path to military rule. Eventually the survivors of the Enclave find a home in the ranks of NCR.

It is not certain, if the NCR got under military rule after destruction of the Enclave and if the survivors of the Enclave found a home in the ranks of NCR. At least one of them, Arcade Grannon, joined Followers of the Apocalypse however. It is known, that the NCR army mimicked some pre-war armed forces ranks also. During long war against Brotherhood of Steel following destruction of the Enclave in the NCR army were present such ranks as:
 * Corporal, eg. Corp. Christina Royce (position mentioned by Chris Avellone only, in fact as: "Corporal, the NCR lieutenant"),
 * Sergeant, eg. Sgt. Larsen, leader of the team escorting the NCR scientists to the Boulder (experience level 8),
 * Lieutenant, eg. Lt. Pierce (Pierce’s position mentioned only by Chris Avellone),
 * Captain, eg. Cap. Pierce (experience level 12), leader of the team escorting Gen. Coleridge, or Cap. Davidson (experience level 25),
 * Major, eg. Maj. Briggs, the 5th Engineering Company CO in 2247(experience level 12) or Maj. Jack Fleming, the commander of the Hoover Dam NCR troops and governor Dodge's right hand man (experience level 15),
 * General, eg. Gen. Coleridge (experience level 20).

Consolidated ranks list

 * Private,
 * Corporal (presence confirmed in pre-war armed forces and mentioned by Chris Avellone),
 * Sergeant,
 * Lieutenant (mentioned by Chris Avellone only),
 * Captain,
 * Major,
 * Lieutenant Colonel,
 * Colonel,
 * General (presence confirmed in pre-war armed forces only, however Col. Sanders had to be subjugated to somebody in CHQ).

Known procedures
Procedures on the oil rig:
 * clearance for some sections,
 * containment procedues.

Procedures at Camp Navarro:

FOB security procedures
FOB security procedures were connected probably with security act 9837-334-27A:
 * FOB is held by Base Commander; his office is off limits to all personnel,
 * a call from base security, when the tanker passkey is suspected to get into wrong hands; then it should be locked up,
 * security detail secures the tanker passkey, after his orders are checked by Base Commander's door guard,
 * the duty officer has to contact Base Commander once FOB is secured,

Alert
Eg. in case of infiltration by intruders. Unknown persons identification papers control.
 * Sound the alarm!
 * Seal the base!
 * Secure all stations!
 * Go code red!
 * Get the backups started.
 * Shut down all classified operations.
 * Secure the system and enable all security passwords.
 * Pointy end with the laser diode goes toward the enemy. Then pull trigger. (technicians and mechanics)

Data protection

 * information could be classified by order of the President,
 * "need to know" rule, eg. information about the oil rig location or authorisation before obtaining the vertibird plans form maintenance,
 * main computer access restrictions,

Other procedures

 * court martial, eg. in case of treason (disobeying a direct order of a superior officer); it can be changed to immidiate execution during alert,
 * soldier identification papers should be carried at all times (eg. checked by officers during alert).

Presidencial prerogatives
According to United States Constitution the President shall be Commander in Chief of the Army and Navy of the United States (Article Two, Section 2, Clause 1). According to Fallout Bible:
 * Presidential Directives could concern armed forces conditioning and testing programs (known example - Horrigans conditioning).
 * Presidencial decisions could concern major importance scientific projects connected with military actions (known example - decision to go take the V13 inhabitants as test subjects for the Project, which scrambled the vertibird unit),
 * Presidential Orders could concern military research and data protection (known example - power armor research).

Main command and Central Headquarters
On the one hand it could be the same thing, on the other hand CHQ could be main command together with its supportive unit (notice: in van Buren "central headquarters" term was used for Fort Abandon, when it was seized by renegade NCR forces for its main base).
 * Main command – name used on PoseidoNet by the Enclave troop,
 * CHQ – col. Sanders’es holodisc addresse.

Features:
 * Supervised by the President or by member of his Cabinet possesing Secretary of War powers (if appointed).
 * Its superior powers concerning United States Chemical Corps are not certain in light of fact, that dr. Curling reported about the Project directly to the Cabinet.
 * Col. Sanders was subjugated to CHQ, when was overseeing the Mariposa Military Base excavation.
 * Usage of PoseidoNet - main command uses the Enclave Vault-Research Control station connected to PoseidoNet, linked with Navarro computer station and Gecko Reactor computer station (notice concerning another big Enclave computers: 3 technicians for the oil rig reactor computer purposes – Atomic Energy Commission, 3 technicians also for Camp Navarro main computer purposes).

Internal security
Military police. Internal counterpart for externally used verti-assault squads. Subordinated to main command.

Air forces support facilities
Two kind of specialists were present:
 * Air traffic control (notice: 2 crew in Camp Navarro - military technician and technician in lab coat),
 * Communication (notice: 2 crew in Camp Navarro - technicians in lab coats),
 * Maintenance (notice: 3 soldiers-mechanics in Camp Navarro), however vertibird maintenance do not have to be subjugated directly to CHQ (eg. there were verti-assault unit and “flyboys”).
 * military specialists - mechanics and technicians (uniformed soldiers, their uniforms look like Leather Armors, mechanics in greased uniforms),
 * 1st and 2nd grade technicians, uniformed with lab coats, like US Chemical Corps members.

Engineering
According to Fallout Bible they are called "construction crews". It is not certain, if it is service branch, unit, subunit or civilian part of the Enclave. Its known activities were mainly connected with civil engineering, eg.:
 * preparing Navarro facitity for military and vertibird purposes (area of the Navarro Refinery, prewar Poseidon facility),
 * excavation of Mariposa Military Base.

It is not certain who took care of explosives during Mariposa Military Base excavation, however it was engineering duty also.

Reconditioning center
According to Fallout Bible soldiers loyalty was reinforced by Presidential Directive through various conditioning and testing programs. Reconditioning center was mentioned by the President as the right place for the Chosen One wandering through the Executive Office.

Training and education

 * At the Guard Barracks bedroom - squad of 8 less experienced guards (150 hp) equipped with Power Armors and Gauss weapons (small arms skill needed only) and 2 troops equipped with Advanced Power Armors (200 hp) could be encountered.
 * Within the Enclave armed forces were at least 4 officers and at least 4 sergeants, who should be educated and trained somewhere (senior staff for CHQ and at least 6 independent units).
 * United States Chemical Corps head, besides of Lt. Col. rank, had doctor of science degree, as well as two other probably USCC members (medical and genetical profile).


 * The Enclave soldiers combat skills (firearms, melee and unarmed) were comparable to skills reached by heavy disciplined and trained ghoul guards in the Reservation (6-15 experience level), the NCR soldiers (the NCR troops in Hoover Dam had 8-12 experience level, Gen. Coleridge's the NCR guards had 15-20 experience level) and Brotherhood of Steel.

US Armed Forces executive branch
Counterpart for prewar US Army and US Marine Corps.

Enclave Control Company
The Enclave Control Company (EC Company) was the only unit responsible for perimeter defense.
 * Part of this company was sgt. Granite squad of 4 experienced troops (200 hp). In Fallout 2 ending part this squad was used as ad hoc support on the oil rig. The squad was equipped with Advanced Power Armors and armed with:
 * Pulse Rifle,
 * Turbo Plasma Rifle,
 * Gatling Laser
 * Plasma Grenades

If the EC Company was responsible for Camp Navarro perimeter defense and was the Enclave basic infantry unit, it could consist also of:
 * Enclave Patrolmen, such as killed in the Mariposa Military Base (among them cap. Pickard and sgt. Bracks); they were equipped with Advanced Power Armors and armed with:
 * Cattle Prods,
 * energy pistols,
 * Plasma Grenades (and probably Plasma Rifles and Laser Rifles also - supermutants equipment).
 * light teams of 4 experienced troops called Enclave Patrols (150 hp), encountered on Navarro perimeter; more rare but still possible were 8 troop squads - 2 light teams in fact; light teams were equipped with Advanced Power Armors and armed with advanced one hand weapons, like:
 * Pulse Pistol,
 * Plasma Pistol,
 * Gauss Pistol,
 * H&K G11.

According to Fallout Bible Melchior, miner form Redding, was kidnapped to work during Mariposa Military Base excavations by the "Enclave patrol" (according his son he went away with some man dressed in metal clothes), however slave workers there were caught by units called "assault squads".

Verti-assault unit


Highly mobile long range assault unit. Because of security purposes the Enclave main command can send verti-assault squad even to as distant place as Gecko. Verti-assault unit was at least platoon size and consisted of at least 2 squads. It was stationed on the oil rig and was absent in Navarro. Its troops are equipped with: Known verti-assault operations were connected with the Project (providing FEV Curling-13 test objects). It was: It is certain, that verti-assault unit uses at least one aircraft and consists at least of two squads, however one squad = one vertibird rule is possible also. Verti-assault unit should consist of at least 14 crews: CO, his sergeant and two six troop squads.
 * miniguns with cartridge cases - Rockwell: CZ53 Personal Minigun or Avenger Minigun (according to Fallout 2 intro),
 * plasma weapons (according to the Enclave main command), which was similar to Navarro outdoor guards, who were wielding Plasma Rifles.
 * seizing of Vault 13 - at least 2 verti-assault squads present according to  Fallout Bible and at least 1 vertibird and 6 troops with 3 miniguns present according to Fallout 2 intro,
 * destruction of Arroyo - at least 2 vertibirds present according to Hakunin.

The oil rig guard unit
Guard unit particularly provided security for Test Subject Holding Level (detention cells). This unit was located at separate barracks on the docks level (Entry Levels). All guards were equipped with Power or Advanced Power Armors. Guard unit consisted of at least three teams (Bravo and Gamma were referred at floating texts, so Alfa team should be present also).
 * Guard Barracks Level - 22 guards:
 * bedroom - squad of 8 less experienced guards (150 hp) equipped with Power Armors and Gauss weapons and 2 troops equipped with Advanced Power Armors (200 hp),
 * storage crew and gym – 2 guards equipped with Power Armors and Super Sledgehammers, a guard equipped with Power Armors and Power Fist (140 hp),
 * armory, boots room and other rooms – 9 guards (200hp) equipped with Advanced Power Armors and mainly big energy weapons,
 * 7 security bots,
 * Detention Cells Level - 8 guards (200 hp) equipped with Advanced Power Armors, 6 bots,
 * total 24 bots in the known parts of the Enclave, including 13 bots present on Guard Barracks and Detention Cells Levels.
 * 2 dead unarmed Enclave Guards at crashed vertibird at Klamath canyon (Jul 2241), one of them – burned, accompanied by damaged Mr. Handy (notice: Mr. Handy accompanied soldiers during secret transactions in New Reno also ),
 * according to Fallout Bible during execution committed on “farmers” family at the beginning of September 2241 Horrigan was accompanied by two the Enclave guards.

Vertibird unit
Aka “flyboys”. Hypothetical transport unit with other then verti-assault duties.
 * There were 3 undestroyed aircrafts encountered in ‘’Fallout 2’’- 2 at Camp Navarro and 1 in New Reno.
 * One of vertibirds in Navarro was probably inoperable [notice: according to the Enclave main command inoperable is something called “unit three”].
 * Total vertibirds number is unknown:
 * it should be enough to transport even 1000 Vault 13 dwellers from Vault 13 to the oil rig during in a short time and to keep stand-by at least one verti-assault squad,
 * there was not enough aircrafts to propel FEV over the mainland (Chosen One’s conclusion),
 * the vertibird number should be adequate to needs and maintenence possiblities of a few hundreds soldiers army.
 * Navarro vertibirds purpose is unknown - there was no Mr Handy bots and there was no verti-assault squad.
 * Vertibird range was at least 175 miles distance between the oil rig and Navarro. Accessible were Klamath, Redding, Gecko, New Reno and Vault 13 also. Other transport issues were:
 * service for Mariposa Military Base excavations,
 * emptying of Arroyo,
 * deathclaws transfer to Vault 13,
 * transport provided for Secret Service operations – huge Horrigan and 2 or 5 other troops (3 known events),
 * barter with Salvatore family, possible everyday, performed by vertibird crew consisted of 2 women soldiers equipped with Pancor Jackhammer and unarmed Mr. Handy (notice: Mr. Handy accompanied guards crashed in Klamath canyon also). According to Chosen One New Reno run was not pleasant duty - probably because Enclavers don't like the mainland (according to floating texts).

Camp Navarro
See also: Navarro
 * Called Camp Navarro according to drill sergeant Dornan. Called a base by all senior staff during an alert. Matt, Brotherhood of Steel member present in San Francisco, called it a base also.
 * Established as a stopover point for the maintenance and refueling of vertibirds. Air Traffic Control and Communication Center were present there also.
 * Commanded by unknown rank elder officer called Base Commander, who was responsible for security of tanker staying in San Francisco docks also (holds a tanker FOB).
 * There were total 40 crew, including 30 troops. Not fully staffed Navarro guard unit (platoon equivalent) consisted of:
 * outdoor squad equivalent - 11 guards equipped with Advanced Power Armors and Plasma Rifles, led by drill sergeant Dornan,
 * indoor squad equivalent - 10 guards equipped with Combat Armors (including Commander's door guard and Snookie, deathclaw's door guard), the only encountered the Enclave light troops (notice: it was planned in van Buren, that the Enclave background character Arcade Grannon and encountered in Utah area the Enclave lost patrol leader would be equipped with the Enclave Combat Armors).

According to dialouge with sergeant Dornan yearly Navarro guard payments were probably 49 currency units (Advanced Power Armor Mk II is worth 25000 c.u., wich is equal to 510 years guard's payments - counted without interest).

According to Fallout Bible no one knows what happened to Navarro after Fallout 2 - with the destruction of the Enclave, the base may not have been able to maintain itself for more than a few months before needing to move on or change its operations. It's unlikely that the Brotherhood of Steel seized it after the events in Fallout 2, because they didn't have a strong military presence up North at the end of this game. They would have been interested in taking it, however - although they would have suffered serious casualties.

Other active outposts
According to AHS-9 the Enclave had hidden bases all over the shards of old California. Presence of the other then Camp Navarro outposts was confirmed by technicians there, as well as fact, that there wasn't any outposts north from Navarro. Other the Enclave outposts: (1) could have some communication facility, as one at Camp Navarro, (2) could be as covered as Camp Navarro with its Gas Station, taken care of by old Chris (notice: quite similar issue to low staffed, "passive" Brotherhood of Steel outposts in the Northern California), (3) could be old government military facilities, as well as MacArthur Army Base, mentioned in van Buren New Canaan design document or could be old Poseidon facilities (notice: according to J.E. Sawyer's Fallout PnP the Enclave remnants were using such locations).
 * "place where replacements for Camp Navarro came form" - hypothetical recruiting outpost (according to dialogues with drill sergeant Dornan and old Chris also):
 * was located on the mainland, but not north from Navarro (replacements got to Navarro on foot, so their departure place can’t be the oil rig),
 * could be covered or hidden,
 * could be old government military facility or old Poseidon facility,
 * should have some person in charge and bureaucratic supply personnel also (referred as "paper-shuffling jackasses"), who were entitled to equip a new replacements with an Advanced Power Armor set (Advanced Power Armor was proper uniform for Camp Navarro guard),
 * could have some communication facility (operated by necessary staff of course),
 * could have not airfield facilities,
 * it sent to Camp Navarro non-Enclave replacements; women and mentally handicapped candidates were allowed (latter ones easy to be reconditioned); replacements could be informed about Camp Navarro entry password and should obtain some identification papers, demanded by Camp Navarro senior staff during alerts,
 * Matt, Brotherhood of Steel member present in San Francisco, didn't inform Chosen One about this place.
 * It is not certain, if mentioned in New Canaan design document MacArthur Army Base, was active. Encountered in Utah area lost Enclave patrol, that was searching MacArthur Army Base, should have some place of departure also.
 * There was no the Enclave presence in the government facilites like:
 * located in old California and near its borders: Sierra Army Depot, "Toxic Caves" Depot, Lost Hills Bunker, West Tech Facility or the Environmental Protection Agency,
 * located on van Buren area: Hoover Dam, the Nursery, Bloomfield Space Center - where the Enclave members were present before the War only, Tibbets prison (or not exactly governmental, but funded by military Boulder Dome).

US Chemical Corps
US Chemical Corps (USCC) was US Armed Forces service branch. Its members were the Enclave's scientific staff, mentioned by Fallout Bible as officers. It was commanded by Lt. Col. dr. Charles Curling. Its dependence on the main command or to CHQ is not certain in light of fact, that dr. Curling reported about the Project directly to the Cabinet. There were 16 generic USCC members present on the Test Subject Holding Level and Research and Development Project Area and at least one generic civilian wearing lab coat on the Guard Barrracks Level, dr. Schreber at Navarro and deserted dr. Henry in Shady Sands. US Chemical Corps known works were:

The Project
The Project – creation FEV Curling-13 lethal virus. Human samples were obtained from the Vault behavioral project. Probably it was also purpose of chems exchange with the mainland.

The experiment on Horrigan
FEV extensivly inoculated and half mechanized object reached extremally increased endurance (999 hp). Its FEV lowered intelligence had to be supported by constant drugs injections provided by permanent armor. Object was armed with ultimate weapons, like: After a few horrifically successful field tests (against local populations in the wasteland probably), Horrigan becomes the Enclave's solution to numerous sticky problems and once again he became Secret Service agent (March 2239).
 * Plasma Gun with burst of 3 x 30-70 dmg,
 * uncharged knife causing 15-30 dmg.

Deathclaws
Since 2235 the Enclave has experimented on deathclaws, attempting to create special fighting units for waging war in hostile environments. Animal handlers were used there. Known intelligent deathclaws were:
 * deathclaw pack (unit) at Vault 13, consisted of 6 mature deathclaws, including:
 * Gruthar, the pack leader (claw 5-10 dmg),
 * Kerith, the current pack mother,
 * four mature pack warriors (males probably, Dar - claw 5-10 dmg, Thearn and Valdis - claw 3-4 dmg, Jul and present only at dialogue file generic deathclaw guard),
 * Goris (development: 134->187 hp, 1-30 -> 1-47 dmg, IN 5->8),
 * 2 baby deathclaws (and 12 egg shells present at the nest),
 * other deathclaws, who were sent into the desert surrounding Vault 13 to check for any escapees or witnesses,
 * other mothers mentioned by Kerith,
 * Xarn, tested in Navarro (claw 5-10 dmg).

According to early versions of Fallout timeline many of the Enclave experiments on deathclaws were tested against Horrigan (year 2235).

Cyber-genetics
Cyber-genetics experiments concerned K-9 and Robodog units and were performed by dr. Schreber and dr. Henry: Basic cybernetic maintenance facility, mentioned in Fallout Bible, was the equivalent of cybernetic janitorial duty.
 * inexperienced K-9 statistics: 127 hp, 16 dmg, 14 AP,
 * inexperienced Robodog statistics: 100 hp, 16 dmg, 9 AP.

Earlier research
According to Fallout Bible:
 * it is possible that the wannamingos were old Enclave experiments or even experiments from before the Great War,
 * in 2198 the Enclave worked on various new technologies, including Power Armor variations; none of these were much of an improvement over the conventional old school Power Armor, and some were actually worse; in 2215 under Presidential Order, the Enclave scientists begin to work on an upgraded version of Power Armor; many prototypes are developed and tested; in 2220 the Enclave scientists develop a reliable version of the Mark II Power Armor (according to sgt. Dornan - Mark II Power Combat Armor); abandoned, technology level 9 Advanced Power Armor project, codenamed ATHENA was planned to appear in van Buren.

Navy issues

 * Despite of fact, that Pacific Fleet was directed there before the War, the oil rig should have own defending naval task force, similar to contemporary aircraft carriers task forces.
 * Chinese fleet remnants are possible also, the example is submarine present in San Francisco.

External defenses
Guns connected with naval IFF system, mentioned by tanker captain - air defense and anti-naval defense were possible, probably similar to another known turrets, like:
 * 5 mm JHP dual miniguns at Sierra Army Depot and .223 dual heavy miniguns inside the oil rig (eg. used for close airdefense),
 * plasma turrets at Navarro or heavy laser turrets in the Vault City (demanding significant amounts of energy).

Naval facilities

 * naval IFF system,
 * empty docking place for PMV Valdez on the oil rig, empty, huge docking area prepared for tankers fleet, no sailors encountered on the oil rig,
 * no coast & docking facilities in Camp Navarro (however it didn't have to be established right in the place of the pre-war Poseidon refinery).

Emergency Defensive Systems
It is not certain what part of US Armed Forces or who, besides the President, is in charge with Emergency Defensive Systems. It is possible, that this is one large defensive system together with the oil rig external defenses. At least 15 security turrets, that wielding heavy dual .223 miniguns with 800 pieces of ammunition, are possible to encounter on the known oil rig levels. It is part of counterinsurgency procedure, controlled by the President and accessible from Data Plex 2000 SmarTerminal at the Entry Level.

Security status levels
Possible security turrets status level was:
 * Armed Alert
 * Normal
 * Deactivated Maintenance

Security override options
Security override options were controlled by the President:
 * Counter Insurgency – in the event of armed rebellion, Presidential Security keycard allows defensive systems to be turned on all, previously loyal, but now threatening units within an area. Defensive systems are programmed to attack most dangerous foe first. Operational - Entry levels only.
 * Emergency Defensive System Shutdown – temporarily shuts down active security systems on a level by level basis. Shutdown starts deep diagnostic.

Cooperation with the United States Secret Service
The United States Secret Service (USSS) was law enforcement agency responsible both for protection of state secrets and (in real world) the President’s protection. Before the War Secret Service could be the part of the United States Department of Treasury, as well as other law enforcement agencies. After the War USSS could became a part of the Enclave armed forces, however its certain status is unknown. According to Fallout Bible:
 * Horrigan has always been loyal to the armed forces (however he was a troop also for some time),
 * there were soldiers, who wanted to or had to accompany him on missions, eg. Sgt. Granite,
 * during execution committed on “farmers” family at the beginning of September 2241 Horrigan was accompanied by two the Enclave guards,
 * Horrigan was present during Vault 13 seizing by verti-assault squads also.

Frank Horrigan was the only known US Secret Service agent. Some USSS agents were visiting the President's seretary office ("hover" according to her float) and they could be presidencial bodyguards also. They were probably equipped with Advanced Power Armors.

During simple assassinations Horrigan was accompanied by 2 troops equipped with Advanced Power Armors and miniguns. During deathclaws' community extermination at Vault 13 he was by accompanied 5 troops. It is significant, that Horrigan and his troops don’t hesitate to enter Shi’s part of San Francisco.

USSS organization:
 * possible person in charge, some office,
 * agent Horrigan as its main field executive force and leader of detached to Agency armed forces squads and teams,
 * perhaps some presidencial bodyguards.

USSS had another system of ranks or positions then Armed Forces also ("agent" position present).

Example of field operation - Mariposa Military Base excavation
According to contradictiong informations at Fallout Bibile:
 * on July-August 2236 the Enclave scientists and chemical corps scour the remains of Mariposa Military Base, while assault squads comb the desert for slaves they can use to mine the Military Base (Fallout timeline),
 * the Enclave held the site for many years, but abandoned it after obtaining the FEV samples.

Purpose: FEV search for the Project. CO: Col. Sanders, the highest rank known Enclave officer. Joint task force: Small 4 tents temporary camp located outside the base.
 * troops - it is not certain what unit were Enclave Patrolmen and Enclave patrol part of, however the most probably is Enclave Control Company. It is possible also, that assault squads, hunting for slave workforce and Enclave patrol, that captured Melchior are the same thing.
 * Enclave Patrolmen - at least one squad, lost during battle against mutated slave miners; supermutants suffered heavy casualties, but 27 of them survived, while 10 the Enclave Patrolmen was KIA:
 * a Patrolman on the 4th level,
 * Sgt. Bracks'es and two Patrolmen on the 3rd level (checkpoint 3),
 * three Patrolmen on the 2nd level (checkpoint 2),
 * Cap. Pickard's and two Patrolmen on the 1st level (checkpoint 1);
 * Assault squads combed the desert for slaves to mine the Military Base. One of them included soldier Frank Horrigan, recently removed from Secret Service after some undocumented psychotic blunder. It is not certain, if it were verti-assault squads.
 * Enclave patrol captured Melchior, a miner from Redding.
 * scientists team of US Chemical Corps aka "pencil necks" (however according to Fallout Bible Enclave scientists were independent form USCC),
 * construction crews (supported by 1st generation super mutant slaves, when excavations begined at 2236 Sept - according to Fallout timeline),
 * vertibird transport.

Inconsistencies at Fallout Bible:
 * single squad was left behind to wipe out the mutated miners, while according to game and the Enclave holodiscs found at Mariposa Military Base:
 * the mutants attack was sudden and two checkpoints were destroyed almost immeditely (7 troops killed),
 * Cap. Pickard with 2 troops was going just to hold supermutants at his checkpoint 3 position, as long as he could (acces corridor to the Base entrance),
 * 10 killed troops were a squad equivalent, but it was not an acting together squad left behind to wipe out the mutated miners.
 * Mariposa Military Base was sealed in Jan 2237, while according to Mariposa Military Base 1st level entry information - the battle against the Enclave Patrolmen has occured recently.
