Not condoning this at all, but it looks like the guy at the front right side of the vehicle tried to shoot out the tires. You can see him take out his gun and aim down.
Insanely dangerous and unnecessary escalation, but at least it wasn't attempted murder I guess?

It could stop shrapnel from shells. Artillery was responsible for the majority of casualties in WWI, not guns.
