Advanced Combat Armor is a more damage and environment resistant variant of Combat Armor.


After the huge success of Combat Armor, the U.S. Military sought to develop more versions of Combat Armor.

Advanced Combat Armor

Starting in the 2060s, the military began testing unique versions of Combat Armor, like the Navy's Frogman Combat Armor, or the HALO combat armor for Air Force usage. However, the two programs did not succeed in the first tests, resulting in at least five deaths, and the Frogman Combat Armor was scratched (the HALO combat armor variant was put on hold until Joint Chiefs of Staff could decide on wheather to continue with the project).

The military then looked at the most important users of combat armor, the Special Forces. They determined that while regular combat armor provided excellent protection; the armor was clunky and was hard to move in, which would hinder the operatives ability while participating in a mission.

So in 2065, the U.S. Army began working on the Advanced Combat Armor with a DoD check, and had a working model by the year 2066. After about 2,000 models were produced, many were sent to the Anchorage Front line, where it was put to extreme use. It was also used in the Gobi Campaign and in other advances into Chinese soil, along with many other operations during the Sino-American War.

After the Great War occurred in 2077, there were many units still located around the wasteland; locked in military bases which kept them in perfect condition because of their extreme durability. Only a few wastelanders got a hold of this, while others perished. The Enclave also worked on the producing more models of Advanced Combat Armor using old schematics.


The advent of Advanced Combat Armor was a significant event in Pre-War Military technology; it marked a connection between powered infantry armor, which was extremely durable but was not very maneuverable, especially with the early models, and with the more flexible combat armor. Created out of comparatively advanced polymers, specifically a combination of fire-retardant plastics and silicon carbide ceramic, the armor allowed stoppage of projectiles and prevention of burns to the wearer. Its segmented design allowed for flexibility beyond that of the solid plates used by standard combat armor—which is the source of a common Pre-War relation of Advanced Combat Armor to Lamellar. By default, the helmet has a mounted gas-mask and respirator system, and its left forearm has a military PIP system and GPS.
