Whilst ref-surfing for info for something entirely different, I stumbled across this rather unique, field-built version of a mine roller truck.
Apparently the Aussies needed a mine clearing vehicle, and looking around at what they had available....none was found.
Soooooooo, being the 'adjust & adapt' buggers that the Aussies are, they proceeded to 'create' one.
The mine 'rollers' are old 55 gal. petrol drums that have had short lengths of steel pipe punched through them, and then filled with concrete. They are then suspended from steel rigging attached to the side of the truck.
The sand bags are both for added weight, and to protect the riders since the vehicles are backed across the minefield to clear it.
Bloody Aussies!


Tread.
Here's another showing them being built....
