KevinB, regarding the wheelchair-bound individual, were you guys able to develop techniques which allowed the individual to participate in drils that require movement ?
The reason I ask is that, being a non-biped myself I have been experimenting with various techniques by which I could achieve movement with a firearm while in my chair, but I haven't had much success. Seems that anything I try ends up in unreasonable compromises between muzzle control, unhindered chair operation (mobility), chair balance (which can become a safety issue), and ease of access of the firearm.
