USCR Behemoth concept art
From their website:
This ultra powerful trooper is the heaviest soldier wielded by USCR, and has the most powerful armor in the game. However, his terrible size and weight comes at a price, as he is one of the slowest soldiers you’ll encounter. The Behemoth wields twin heavy assault cannons on his weapon rack, and carries a massive combat hammer. His primary tactic: to suppress you and then smash you to bits.
