That is nuts.
Having been on the receiving end of a mk40 2.75 rocket from a Huey gunship in '68, I can attest that the noise and seeing the incoming rocket trail coming at you is an 'OH CR*P' moment and all you can think is how far can you dig your face in the dirt.
The KA50's B8V20 is a podded launcher that holds 80mm Rockets. A little bigger than the 70mm mk40 used by gunships in Vietnam.
