There seems to have been a lot of thought to making a coherent whole out of this. Looking at the way the components are arranged...

Chrono Miner - becomes the torso and left shoulder
IFV - becomes the right shoulder, with launcher, machinegun, and repair arm attachments mounted to different shoulder points
Grizzly Tank - becomes the left arm, turret attaches to the shoulder
Robot Tank - splits to become attachments on the wrists
Mirage Tank - becomes the head
Prism Tank - becomes the waist and upper legs
Battle Fortress - splits into the legs and feet
