Mechs: Pretty much something like XANAX's mechs. Different class like Light, Medium, and Heavy.
Hardsuits: They work like Cyborgs, but with a little more armor and more human.
They can take a few hits and pack a punch, but they require barracks to provide pilots.

Footsoldiers: Starting from just-above-scavenger tough guys to holy-crap-get-out-of-there guys in hi-tech armor, foot soldiers are your all-around soldiers. They require barracks to train and produce. The starting classes would be Marksmen ,Assault, Heavy,Engineer and Medic. Adding these will probably change the gameplay of WZ2100.
