@ subbo, i let my mate Mark do the sling for me and he was in infantry for 9 years, so i'm pretty sure it's done right! as for the boots, it was a pretty mucky day and the pic was done towards the end of the it, the trousers are high as i kneel alot and as you kneel, the trouser come up (as you expect them to, and the knee pads stop them coming down)
cheers
