AI gunners (including autonomous vehicles) often fire weapons (GMG, HMG, cannons) in salvos. The AI knows exactly when a target is down and immediately aims somewhere else ("no target" neutral, next target) while some rounds of the salvo are still being fired. This appears to happen with vehicles and infantry alike.
This is leads to friendly fire, collateral damage and ammo being wasted. I created this ticket after a friendly Marshall fired the rest of an APFSDS-salvo into the back of my APC.
