A Styer AUG platform with ridiculous accessories.
Ridiculous, but curiously devastating. This might be one of the aptly-named one-man-army weapon system. The flamethrower, however, is possibly redundant, since there is already a close range weapon (the underbarrel shotgun).
Outta shells? No problem... or ya just wanna set it on fire. Shotgun undermount mainly used for breaching. Flamethrower mainly used for room-clearing or scare-tactic to relieve tangos of close-range cover.
