Winterized T-51b Power Armor

The winterized T-51b armor is a unique armor in the Fallout 3 add-on Operation: Anchorage.

Background
The suits in Anchorage had to be adapted for the cold and have a US Army logo and flag decal on the back. It also has two stars on the front of the shoulder plates and has the serial code DiV:5128417 USA Army on the left front.

Characteristics
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.

Locations

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

Behind the scenes
The winterized T-51b power armor was created by character artist Jonah Lobe.

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 likely 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 (helmet excluded) will confuse the game into thinking you picked up the T-51b power armor from Fort Constantine and will complete 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 multiple head items at once, like hats or bandanas.
 * 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.
