Is there a reason every rifle wasn't equipped w/ a strap and soldiers allowed to swing over their shoulders when on the march? Wouldn't this be more comfortable? Easier on the body? I've never marched 10 hours alternating from support to shoulder arms but I have to imagine this is tiring. Every little advantage would help in combat.
Also, did soldiers ever pack their rifles and ammunition in the wagon train to allow them to move super fast or allow them to arrive fresher? Obvious disadvantage being what happens if you get ambushed, you can't fire back. But there have to be ways to screen w/ cavalry or otherwise only use on established safe routes where this would also be an advantage (ie. Chasing Lee into PA). Again, if your men arrive a little less tired, every little advantage helps in combat.
