As we know in the Civil War, when ammunition was exhausted regiments would fall back and resupply or loot the dead and wounded for rounds. They did this by finding supply wagons. War of Rights needs this mechanic.
Just last night alone, no less than half our 12 guys ran out of ammunition at one point or another and had to either 1) wait for a bayonet charge, 2) scout and not shoot at all or 3) run to a Union line across the battlefield and F9 die costing our team valuable tickets. More than once our guys had to leave good cover and were dropped while running to get to a Union line trying to F9 die in line thereby costing our team an out of line ticket. It's a somewhat ridiculous decision to have to make as a commander as to what your guys should do in that case and an immersion killer. Surely having an ammunition resupply closer back near spawn can be easily implemented. A guy runs up to a wagon and it resupplies his cartridge box with a fresh set of rounds.
That is more inline with the commitment to authenticity by the devs and last night was not an isolated case. My guys are having to do this week after week and I can only assume that other regiments are running into the same issue.
