Fallout 3 Power Armor

The T-45d Power Armor was the first version of Power Armor to be successfully deployed in battle by the United States in 2067 during the Sino-American War and is the most basic model of Power Armor in Fallout 3.

Originally developed and manufactured for the United States Army by American defense contractor West Tek, it is currently employed by several factions, including the Brotherhood of Steel and the Brotherhood Outcasts. The Enclave however uses their own types of power armor called Enclave Power Armor (Advanced Power Armor Mk II), Enclave Hellfire Armor (Broken Steel) and Tesla Armor. Each of these factions have their own variants of Power Armor.

Background
In 2067, the first suit of T-45d Power Armor was deployed in Alaska during the start of the Anchorage Reclamation in the midst of the Sino-American War. This Power Armor was incredibly effective against Chinese tanks and infantry. Nearly two centuries later in 2277, around one hundred T-45d suits were discovered by the Capital Wasteland Brotherhood of Steel in the ruins of the Pentagon and were extensively used by Brotherhood Knights and Paladins.

The T-45d lacks the mobility of later Power Armor models (such as the T-51b Power Armor) because of its less advanced servo design; as a result it limits the wearer's agility. While the T-45d armor is similar in its overall shape to the more advanced T-51b Power Armor, it is significantly less advanced than its later counterpart, and uses riveted steel plates instead of plastic composite materials in its construction.

Variants
Wearing Power Armor requires the player to receive Power Armor Training by talking to Paladin Gunny in the Citadel, by completing the Anchorage Reclamation simulation (Operation: Anchorage), or having acquired Ashur's Power Armor and left The Pitt (The Pitt (add-on)). In addition, it can be unlocked via console commands in the PC version with.

T-45d Power Armor can be repaired using components from the T-51b Power Armor, but the reverse cannot be done. This might be the result of a bug or it might be the fact that the T-51b Power Armor is simply more advanced that its counterpart and uses parts that cannot be substituted with T-45d parts.

Power Armor
Regular Power Armor can be acquired from the Capital Wasteland's merchants, although they rarely appear in stock. You also receive a complete suit of Power Armor in 100% condition from Sarah Lyons at the beginning of the game's final quest, Take it Back!. It can also be acquired from some fallen Brotherhood of Steel members. Power Helmets can be found from merchants and fallen Brotherhood of Steel members.

Brotherhood Power Armor
This variant is found on most fallen Brotherhood of Steel members and has the same appearance and attributes as regular Power Armor. There are no differences other than the name and that it will not appear in a merchant's stock (This armor is very rare since most Brotherhood members' inventories are placed with "normal" T-45 Power Armor).

Outcast Power Armor
Brotherhood Outcast Power Armor can be acquired from the corpses of fallen Outcasts and from Fort Independence. However, having Outcast variants in your inventory (equipped or not) when speaking to Protector Casdin will cause him to confiscate the armor unless you have gained the Outcasts' trust. Outcast Power Helmets can be acquired from fallen Outcasts.

Lyons' Pride Power Armor
Lyons' Pride Power Armor is the same as regular Power Armor, except that the Lyons' Pride insignia is on the shoulder instead of the standard Brotherhood of Steel insignia. It can be acquired from Sentinel Lyons before the final assault on the Jefferson Memorial in the quest Take It Back, or from the corpses of dead Lyons' Pride members or reverse-pickpocketing: Sentinel Lyons, Knight Captain Gallows, Paladin Vargas, Paladin Glade, Paladin Kodiak and Knight Captain Dusk.

Army Power Armor
Army Power Armor & Helmet can only be acquired on the PC version using console commands or modified save files through Hex modding. It has a US Army band on each shoulder.

Prototype Medic Power Armor
This is a variation of the Army Power Armor and can only be found in the Old Olney sewers. This suit automatically applies Med-X and can alert you about threats in the area.
