Those gigantic streaks in the lower right are shells from tanks. They certainly aren’t tracers from rifles.
You’re right to press me for details on the “tank” part. I don’t know if the shots are from tanks. But they’re so large that it rules out foot soldiers, so it’s some kind of vehicle-mounted gun.
