American soldier (Operation: Anchorage)

American Soldiers are the backbone of the U.S. Army and are your main allies in the Operation: Anchorage add-on for Fallout 3.

American Soldier
American Soldiers wear Winterized Combat Armor and are armed with R91 Assault Rifles. They have superior health and armor compared to their Chinese counterparts, but they have inferior weapons and are vulnerable to Crimson Dragoons and snipers.

The basic U.S. infantryman has about twice as much health as a basic Chinese soldier, and is about on par with a Chinese special weapons unit (and also roughly on par with an Enclave Soldier) in terms of skill and durability.

American Sniper
American snipers wear Winterized Combat Armor. They utilize a sniper rifle. They are effective against Chinese infantry.

American special weapons units are about on par with Chinese special weapons units in terms of skill and durability. Unlike their Chinese counterparts, American special weapons units do not have increased skill or durability in relation to the basic infantry unit.

American Inferno Unit
American Inferno Units wear Winterized Combat Armor and carry a flamer. They are effective against Chinese infantry and entrenched positions. They are always male, but their race is random.

American special weapons units are about on par with Chinese special weapons units in terms of skill and durability. Unlike their Chinese counterparts, American special weapons units do not have increased skill or durability in relation to the basic infantry unit.

American Launcher
American Launchers wear Winterized Combat Armor. They are armed with a Missile Launcher. They are effective against entrenched positions and Chimeras.

American special weapons units are about on par with Chinese special weapons units in terms of skill and durability. Unlike their Chinese counterparts, American special weapons units do not have increased skill or durability in relation to the basic infantry unit.

American T-51b Unit
This troop type wears a Winterized T-51b Power Armor and is armed with an R91 Assault Rifle. They are only seen patrolling in and around the U.S. Army Field Headquarters. They are always male, but their race is random.

Oddly, unlike their powerful counterparts seen during the final battle at the Oil Refinery, the American T-51B Units at the U.S. Field HQ are only slightly more durable and skilled than the basic U.S. infantry soldiers (although they do have superior armor).

Power Armored Soldier
Wearing Winterized T-51b Power Armor, Power Armored Soldiers are armed with AER9 Laser Rifles, 10mm SMGs, R91 Assault Rifles, Chinese Assault Rifles, super sledges, Scoped Gauss Rifles, miniguns, flamers, and Fat Mans. They are very effective against all Chinese forces. Their only weaknesses are pulse fields.

Most of these appear in the final confrontation with General Jingwei. Power Armor Soldiers are very powerful, with high health and good armor giving them slightly better durability than even a NPC Companion or Super Mutant Master.

U.S. Paratrooper
Only one U.S. Paratrooper appears in the simulation, dropping from the ceiling of the Cave Outpost in The Guns of Anchorage and leaving his Scoped Gauss Rifle for you to take after his Winterized Combat Armor fails to protect him from Chinese soldiers. Your character in the simulation is also a paratrooper.

Notable quotes
"U.S.A!"

"The Stars and Stripes Forever you Commie Sonsabitches!"

"U.S.A Forever!"

"Welcome to Alaska, Commie!"

Additional battlefield support
It seems that General Chase had access to prototype VB-02 Vertibird Gunship Support during the campaign, although this might have been one of his additions to the simulation.

You may also kill captured american soldiers with no negative repercussions and a gain of experience.

Bugs

 * If you take too much time while trying to kill General Jingwei, Power Armored Soldiers will attack you. This happens as the player character is assigned a temporary affiliation with the Chinese Faction so the dialogue with General Jingwei can occur - otherwise he would be forced to attack on sight by his AI. Although the Chinese turn hostile after the dialogue (as, in game terms, you have angered or attacked them) the affiliation remains and the American Faction, appearing only as the Power Armored Soldiers, are hostile due to this affiliation.
