Just look at some of the vehicles that aren't burt out. Some of them look more or less fine at first glance. Notice that all their tires are flat.
I remember seeing a video filmed by a Russian who's vehicle had been hit by a HIMARS strike, and he showed how the vehicle looked fine at a distance, but up close you could see that the whole thing was perforated by tiny holes. These little holes were made by thousands of small tungsten balls moving fast enough to pierce clean through the engine block.
It appears that all those flat tires are indicating that those entire trucks, and anyone who was on them, are similarly perforated.
