Great piece, I have the dubious distinction of being the first member of the Irish equivalent of the Territorials to get a license to drive an AML 60. I may or may not, have been legally old enough to drive one on the roads as I may have 'adjusted' my birth certificate to join a Cavalry Reserve Unit.
For authentic detail, you need to get a bunch of battered French army metal water bottles and jam them round the exhaust pipes in the boxes at the back, then shove them up your jumper when you are out on ops in the dead of night in the middle of winter. That and a bottle of rum was considered essential kit.
It's not difficult if you try hard enough! The instruction manual showed a diagram and the diagram was printed 90 degrees rotated on the page.. so with no 'gates' on the box you can't feel whete you are ( lots of free play) so it's guess work when you are a novice!
