Winterized T-51b Power Armor

The winterized T51-b armor is a unique armor in the Fallout 3 add-on Operation: Anchorage.

Characteristics
It is one of two armors used by U.S. soldiers (the other armor of choice being winterized combat armor) in the Anchorage Reclamation simulation and can be obtained from the VSS weapon cache in the Outcast Outpost after completing the simulation.

Unlike the regular T-51b power armor found in Fort Constantine, the winterized version lacks rust, features a snow-camouflaged paint job with US livery, and has 45 damage resistance as opposed to the regular version's 50.

The armor is fitted with a back-mounted TX-28 MicroFusion Pack which generates an output power of 60,000 Watts to power the HiFlo hydraulic systems built into the frame of the suit. Made of a poly-laminate composite, the outer shell of the T-51b is lightweight and capable of absorbing over 2500 Joules of kinetic impact. The 10-micron-thick silver ablative coating can reflect laser and other radiation emissions without damage to the composite subsurface, and the eyeslit for the helmet is made of bulletproof glass to protect the wearer from any projectiles.

Locations

 * Can be seen on armored infantry in the Anchorage Reclamation simulation.
 * Can be found in the VSS vault after completion of the simulation.

Bugs

 * The version given after completing the Anchorage Reclamation simulation is the "sim" version, rather than the intended "wasteland" version. Among other issues, the "sim" version has abnormally high health—close to 10 million hit points—and as a result will never become noticeably damaged. The armor can only be repaired by merchants.
 * Taking this armor while doing the quest You Gotta Shoot 'Em in the Head (the helmet excluded) the game confuses this for the T-51b power armor from Fort Constantine and completes the mission. This also rewards with the achievement or trophy respectively. Mr. Crowley will no longer speak to you after getting the armor, other than the remark about stealing what was rightfully his. One way to avoid this is to keep the winterized version in storage (e.g. in the locker in the Megaton house or Tenpenny Tower suite) while completing the quest, or hand over the keys and beat Crowley to the armor.
 * The power helmet can be worn with another head item, like a hat or a bandana.
 * Sometimes, when equipping the power armor (the helmet has not been confirmed) the power armor will appear invisible, leaving only the arms visible, but it will still have the 45 DR of the suit. Un-equipping and then re-equipping the power armor can fix this.
 * When the power helmet is equipped and chinese stealth armor is worn, your body may become entirely invisible (do not mistake for chinese stealth'invisibility powers") and your helmet will look like it is floating yet you can still move and fight. To fix this take off the helmet and your character will be fixed.
