Really? I've been to American CW "re-enactment" camps where the smell of horse shit was deliberate, bloody bandages (real blood) were thrown on the ground around a bloody "operating table" made from a door covered with a sheet, the instruments bloody. Two of the "patients" were actual amputees with their stumps dressed and "bloody" (this time from stage blood). Others were "ill", laying on their blankets with (fake) vomit around them. Yes, there were "coffins" stacked up.

All that was missing were the bullets and the fleas.

Some "Disneyfication" is needed -- you cannot reproduce (legally) an actual battle with live ammunition, the shouting, the confusion, the wounded, the traumatic amputations, the spurting blood, the vomit, the beshat clothing, the bayonet and sword wounds, the smell. God, the smell!

But you CAN do better than people in freshly cleaned uniforms marching as if on parade.

Been to the battle, done that, got the disabilities.
