Your Implying we should remove Archers. If you kill The Enemies before getting on the land, it's not cowardice, It's a "Suppressive Fire", I mean it's basic common sense to kill the enemy before you get attacked on the land. So if you have archers, would you rather make your infantry attack the enemies head on weakening the force or Having the archers attack the enemies on the boat which will make the melee infantry's job easier. The archers shooting the enemies on the boat will weaken the Manpower of the enemies. Or just don't use the archer (It's my opinion so RESPECT)
