It uses a US Army M20 howitzer mounted on an M1152 expanded capacity hummer. It has also been demonstrated at an AUSA conference. Mandus Group teamed up with AM General for this effort. Mandus is a fairly new company formed in 1998(?). They got their start in the hydraulics business and claim to have the best hydraulic engineers and techs in the country working for them. They claim a 70% reduction in recoil. They also claim you can shoot and scoot in 30 seconds.
Below are the specifications. As it stands now traverse limits are 180 degrees, elevation -5 to +73 degrees.

I'm leery, but also impressed. If the Air Force can fire a 105 from an aircraft then why shouldn't this be viable? And why not mount it on a Stryker - or the LAV-25? Could a HEMTT or another platform possibly be used for a 155?
Fire away!
