I've noticed that in the screenshots for the Artillery that there's a slight historical error in that the #1 man (sponger) covers his ear (left) that is facing AWAY from the cannon leaving his (right) ear completely exposed to the blast of the cannon which would cause extreme hearing loss.
Historically the #1 would cover his ear that is facing the cannon.
You can see a good example of this in this video with live fire canister at the timestamp 4:11.

For the sake of historical authenticity I'd like to see this detail improved.
Also just as a suggestion I thought it'd be kinda cool to add a photographer class for the drill camp.
Could be dressed like John Reekie.
Just a suggestion.
