Carapace Armor (Long War)
Our Carapace Armor was designed to offer substantially better protection against the alien plasma weaponry through the use of their alloys. Tests indicate a substantial survivability increase relative to conventional body armor."
There is a good chance this armor kit will probably be your standard issue armor throughout the game. While it might slow you down it does keep your soldiers alive and can even take a critical hit, provided it is not from a plasma cannon.
