DPM trousers, black wooly pullys and drab green hats... Are you on Acid? Have you even worn a Wooly Pully other than for your Cadets parade, either that or you've read one to many Commando Comics. Go out onto the hills in the rain with your Black Wooly pully and see how long it takes for you to go down with a Cold injury. Apart from said Wooly Pully making you look like a Tescos Security Guard, it's also a sponge to wet weather and uncomfortable to wear on camp let alone in the field.
To the addon maker, do yourself a huge favour and avoid the "Call of Duty SAS types" advice you seem to be getting, really just avoid it. If you want some decent advice feel free to drop me a PM with any questions and I'll be happy to help.
