Not sure but its a fairly standard process:
- under suit / neck seal
- thighs
- boots
- shins
- torso (chest, back, an, kidney, butt. Open it on the right side, undo right shoulder strap to get head through, do up shoulder, close up right side)
- belt around waist / holster / thermal detonator
- arms (shoulders might be attached already)
- lower arms
- gloves with hand plates
- helmet
- test other accessories like voice amp, mic, blaster etc
- done!
