In other words, a Killer Thrust Reverse system. I somehow doubt the 100-knot figger, but I'm sure the effect IS substantial.
Actually, the recoil is greater than that. An A-10 flying level at maximum speed and with 100% thrust will stall from the recoil of a 5 second burst (250 rnd).
This "machinegun" is the size of a minivan.
