American war of independence = AWI
Ok a list.
1.The rifiled musket could hit a man at 600 yards, probebly only 1 man out of 100 could do it, so a regiment of 600 men would get 6 hits, lets say 10 because if random bullets getting lucky.
2. If the unit is infantry it would get hit sevral times before making contact, and bt then could have lost a 100 or more, in theory.
3, most soldiers didn't shoot to kill, they fired above or below the target, this is constant no mater how good the weapon was, most soldiers didn't use it to kill, it was like that in roman times, middle ages, thirty years war, napoleonic wars, acw, ww1 and ww2. Only during the vietnam war and later with new training would a majority of soldiers shoot to kill(and that brought with it a whole bunch if new problems )
4. At 100 ish yard, the hit rate of a rifled musket and musket is about the same, again going to the, it's the shooter not the weapon that counts.
5. Terrain, A, cav doesn't charge in woods, water or hills, most acw battlefields wers that. B, a rifle that can kill at 600 yards doesn't help in a forest were you can only 70 yards.
If America looked like Europe, there would be less cav then during the napoleonic wars. (Kinda like FPW)
But not to that extent.
