"MRSI the new buzzword for "Time on Target"."
It's a one-gun ToT now. We called them Hi/Lo's. I dunno. Need a good A.G. at the elevation hand-wheel and that's about it. Four rounds easy on an 105mm w/ data figured and charges pre-cut (absolute safety violation IAW AR 385-63
).
G.G., if you could get off six on a 155mm I'd easily believe it.
