Every rifleman a sniper? There are times for volume of fire, too. > Note that 20mm rounds are more than twice the wps of 7.62mm > rounds, but 20mm cannons still replaced 7.62mm MGs on fighters. Because 7.62mm couldn't do the job any more. Make the gun big enough to punch through the suit, with a margin of error, but no bigger. German WWII bomber interceptors went to 30mm when general- purpose fighters had 20mm, http://en.wikipedia.org/wiki/MK108 > > My suit has DR 360, but there will be softer targets on the > > battlefield which do not rate the big guns. > > DR 360 laminate? > > So I figure 6dx20 for reliable penetration (given the curve of > 6d6), so that works out to: 6dx7(3) for APFSDS, 6dx4(10) HEAT > or 6dx8(5) HEDP required to hole a suit. The 40-lb. blaster does 6d*25, which leaves a margin to deal with an up-armored suit.
