Damage/Alloy Armor

Alloy Armor is one of the four health classes of the Grineer. This is one of the two types of armored health classes that receive a damage reduction from the Armor attribute; the other armored health class is Ferrite Armor. Alloy armor is typically found on the heavy-armament Grineer troops, such as the Napalm and Bombard.

Presumably, this armor is made from Alloy Plates. If you look carefully, there are five Grineer letters imprinted on each Alloy Plate that, when translated into English, read "Armor".
