This is about last year's tour in the Stan by the Royal Anglians. It shows quite clearly why equipment has to be denied to the enemy. It is just not practical to potter around the Green Zone with chainsaws.
Wokkas only go in there with Apache escorts and then only to pick up T-1 casualties. The bravery of all involved is astonishing.
