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.
It’s definitely not the kind of thing you want hitting a nuclear reactor.
They're typically equipped with heavy weapons that are smaller or less powerful than tank main guns but larger than something that could readily be carried by a soldier or two.
