The scorched Sierra power armor is a suit of T-45d power armor that has been modified by the NCR for its officers. The left shoulder pauldron has been replaced with a hairless, taxidermized bear's head held in place by a green mantle with two bronze star medallion clips. The back-mounted power cylinders have been replaced by a more streamlined box unit with glowing green panels which also appear on the forearms. The armor itself is slightly blackened due to the nuclear detonation. The bolts on the armor appear to have once been plated in gold-flake along with chipped gold-flake trimming all around the sides of the armor.
It provides a Damage Threshold of 24 and a bonus of Fire Resistance +25 and STR +1. Most notably, it is unique in giving a health regeneration bonus of 2 HP per second. It can be repaired with T-45d and T-51b power armor variants, as well as Marked Men trooper and patrol armor.
Despite its appearance, the suit is not considered faction armor, therefore it can be safely worn in any location without repercussions.
The armor's listed effect "HP +2" grants the wearer regenerative health, at a rate of 2 HP per second. This effect applies to non-player characters, such as companions, who wear the armor.
The bear head doesn't appear to be a mutated bear's head, which is strange seeing as in how most if not all bears in the Fallout universe are mutated.
The armor looks as if it once was painted with gold trim to enhance the look of the user in the armor presenting a high level of command and importance.
The armor lacks the -2 agility found on normal T-45d power armor.
The armor has only a +1 strength compared to the normal T-45d power armor that has +2.
The armor's health regenerating effect combines with the Monocyte Breeder to allow for more effective healing.
Behind the scenes
The armor was inspired by a mod made for the PC version of New Vegas. In an interview, Chris Avellone said "The armor was something one of the staff members saw, and we thought it would be the coolest thing to put in one of the last add-ons for Vegas."
Unused resources exist for a matching helmet to go with the Scorched Sierra power armor, notably featuring a green glow coming from the visor area. The mesh and corresponding textures are fully complete, but were not incorporated into any armor or other console-obtainable item.
