my friend in the royal engineers said their pretty bullet proof as they used to make a ramp on exercise with their engineering tank and all sit down and let the stolly drivers see how high they could get off the floor (all 6 wheels) and all sit around and mark them just like pop idol, and they didn't break them!
Its a hard life, but somebody's got to do it

The white lines on the hubcaps are to show you when you break an axle (they should all line up)
Didnt know that, i saw one at a vintage rally once and wondered why they were there
