Catalyst 302 (known also as M350 Heavy Armor) was a type of armor used extensively by vessels of the United Nations Space Command Navy. It is a multilayer battleplate of primarily classified composition, though it is known to be comprised of Titanium-A, lead foil, and TerraGen, among other materials. It is worth noting that its name was created through a randomized digital selection program and is not directly related to the armor itself in any way other than name.
