Enclave soldier

Enclave Soldiers are the main Infantry of the Enclaves' Armada and are currently the toughest,strongest and fastest Human Enemy the Player can face in Fallout 3. In short, when you see that "Black Devil Power Armour"...run.

Their equipment in the field greatly varies, but tends to be superior to enemy factions, namely the Brotherhood of Steel. In the 2240s they usually wore Advanced Power Armor or its Mark II variant, and were equipped with either P94 Plasma Rifles, Gauss Rifles, or Pulse Rifles. In the 2270s, they switched to Advanced Power Armor Mk II and Tesla Power Armor; their weaponry of choice was usually Laser or Plasma Rifles. The soldiers are highly trained troops. Sometimes the soldiers are called "one of earth toughest".

In Fallout 3, most Enclave Soldiers wear Advanced Power Armor Mk II (Enclave Power Armor) are armed with Laser Rifles or occasionaly Laser Pistols. Enclave Soldiers equipped with Tesla Power Armor often carry heavier equipment, typically being armed with Plasma Rifles or Gatling Lasers, and occasionally carrying Miniguns or Missile Launchers. Enclave Soldiers in Tesla Power Armor become more common at higher levels, and usually appear in very specific locations. For example, guarding the exit from Raven Rock, or serving as Colonel Autumn's personal bodyguards. However, they still appear in the Wasteland on patrol and in Vertibird Gunships assault units, as well as guarding camps.

Enclave Soldiers in Fallout 3 often appear in patrols of three to six soldiers, sometimes supported by an Officer. Heavily defended outposts include up to an entire company, including officers, caged Deathclaws and even Vertibird Gunships. Enclave Soldiers use tactical training in combat, such as flanking. They also have somewhat more health than comparable factions, namely Brotherhood of Steel soldiers or Talon Company Mercenaries. This, matched with their Power Armor and Energy Weapons, make them superior opponents to any faction in Fallout.

Behavior
Sometimes Enclave soldiers can be spotted in random locations around the Wasteland doing pushups in groups of three while a Officer oversees the training. Ussually when doing this the soldiers will have their Helmets off.

Enclave Soldiers side with no other faction than thier own in combat(with the exception of the Mind cotrolled Deathclaw)and so are hostle to anybody in the wasteland they detect. There have been several reports on this on both the xbox 360 and playstation 3 consoles. Some examples are:

Enclave Soldiers attacking a group of wandering Ghouls unprovoked.

A pair of Tesla armored soldiers being dropped off by a vertibird near a Raider camp and killing all the inhabitance.

The town of Arefu being assulted by an Enclave Squad consisting of Three Soldiers, an Officer and a mind controlled Deathclaw.

An interesting side note is that Enclave soldiers will not persue their target if it has fled into a nearby building or thier home which gives an odd impression. Although the Enclave Faction is a mainly consisted of cold-blooded extremists, unlike the blood thirsty Raiders who embrace their violent nature, the Enclave see themselves more as a Wasteland Police Force who Judge wether a person lives or dies on the grounds that if they are asset or an obstacle to the mission.

Bugs

 * Occasionally Enclave Soldiers and Enclave Officers found randomly in the Wasteland will appear as friendly to the player. If you speak to them they will either say "Hey There." or "Yeah.." and the only dialog option is "See You later". This has been reported on the PS3, Xbox 360, and PC versions of Fallout 3
 * Similar to the above bug, but it appears almost any Enclave Soldier wearing Tesla Armor and armed with a Missile Launcher will be friendly towards the player unless attacked. The soldier can be communicated with, but the only dialogue option is "See you later". They spawn randomly in Enclave camps, patrols, or Vertibird drop-offs.

Appearances
Enclave soldiers, like the Enclave itself, appear in Fallout 2 and Fallout 3.
