Unusual use for a Cab 12 C60L

[Lynn Eades]

Is the high bit armour for the driver? I see a spare "roller" on the back. (made of concrete?)
I think the roller was built to be somewhat "sacrificial"
The "spikes" are quite long, which would "tend" to make any blast more of an "air" blast (more bang, less damage)
The whole lot looks rather "jerry rigged". Something that was made from a sheet of corrugated iron and imagination. Something that the C.O. asked for, but was not on the CQMS's CES.

Hows that Mike? .....come to think of it, it has an Australian look to it.
