Saw an RT article on this very fact from the Russian perspective (with a mention Ukraine did it too). That was oh 1-3 months ago? They mentioned they could strap a 1500kg bomb or even two to some of them and drive them right into a Ukrainian trench or dug-out. The vehicle they showed in the example video was 6 or 8 wheels I think and had room for carrying a bunch of weight on top, it was low to the ground.
