What DPFLH said. Infinite ammo has a bug where if you turn it on before a unit has fired their first shot, it'll glitch. For infantry, the soldier will be stuck on a reload loop after firing one shot. So he'll fire one shot-reload-fire-reload etc. For an armed vehicle, it's much worse. After firing a single shot, the entire gun will jam up. You can't reload and you can't keep firing so you essentially break the weapon. Turning off the Inf ammo option, allowing a soldier to shoot normally, then turning it back on works for infantry, but for vehicles, the weapon stays broken. Hopefully you can fix this MrAntiFun as your trainer is indeed the only one out there right now. Please and thanks!
