It's a BFG. The payload weight is 2.2 pounds, so 2.2 pounds of explosive or whatever, with a range of about 700m. Since it has no backblast it can be fired from vehicles and confined areas. At 75mm this is just a miniature prototype, the production version is meant to be 84 mm. It would be good for a portable anti-tank system, or riot control, and I can't wait to see one whipped out in a movie gunfight.
