I know I have alot on my plate, but I decided to make the first mech in the pack.
It is actually meant as a type of heavy power armor which I believe is smaller than the Proto titan.
Backstory- Sometime around the early 2028, a small company known as Armorer Corporation (seemed legit name) decided to make an improved combat suit for the military. Current suits were still the traditional camoflauge and kevlar vests underneath, and terrorists had autocannon trucks so they looked to counter the problem by looking at different types of protection. Eventually by June 2028 they had made the first suit of armor that was only a meter or so taller than a grown man. It featured titanium alloys, advanced computing system for identifying individuals, and an optic for when bigger weapons were used (such as a custom made 76mm gun from a scrapped M4A3E8 Sherman, that could be fired by the individual.) Eventually it was tested in battle and allowed soldiers to take direct hits from RPG and Stinger rounds while being unphased.
However, it had flaws such as:
-Running out of fuel (fixed in Mk2 variant being solar powered, Mk3 using nuclear fusion cores)
-Gun systems not being reliable
-Terrortits "stealing" them from nearby countries
