then go and crawl through mud, climb all over the carrier, get oily and grubby.
then it will look legit
interesting about carrier drivers, I had an image of my grandfather in his KD kit with what looked like a dinner stain on his jacket just above his belly.... always thought it was a touch shabby on his part
fast forward to 2014..... got out of my carrier wearing my KD jacket looked down... same blob same place
it was a dab of grease from the steering gear which had dropped onto the bottom of the steering wheel after a very very hot day, then transferred onto my kit.
needless to say I left the mark where it was, and I tipped my hat to grandfather.
carrier crews are a scruffy lot.
