"This diagram demonstrates two weapons used by specialist units for close combat and raids.

The topmost weapon is the PC-505 "Buster" personal siege cannon which is used for armoured targets, armoured doors, and thick walls. It's weight means only stronger units or mechanically assisted units can wield it and survive the recoil.

The bottom weapon is the MW-104 "Xavier" arm strapped heated chainsaw which uses a primitive diesel combustion engine, and two voltaic cells to spin and heat the chainsaw for close combat situations or for cutting through wooden structures. Use on actual trees nnot recommended due to fire risk and fuel combustion."
