Inspired by the Famous Spiritus Systems's MK4 'The Chassis" is inspired to be equally modular as the Spiritus systems MK4 but allowing the same set of inserts being used with this system. With interchagability one can cross platform, and utilize what they already have, or simplt have multiple sets ups. 
Slightly wider than the Spiritus System's MK4, this Chaissis also has a build in Map/ dopcument/ admin pouch behind the large pocket. This gives extra storage, and even space for a cooling pad.
