From the preview:
First up is the Thonian Guardian. Armed with Scattergun and Stun Grenade, these quick-strike units are ideal for taking out squads of lightly armored units or inhibiting Heavily Armored ones.
Next is a quick render of the Ordhren Havok for scale comparison with the Soldier. The Soldier stands just about 35mm and the Havok a towering 80mm!
