Born and raised here in Texas. I've never actually been to the UK but I have always wanted to visit.
Back to the topic of A-TACS.
From what I can tell about the majority of your skirmish sites that I've seen in pics, A-TACS would work pretty well. A lot of the dead undergrowth will complement the color scheme great. A-TACS was never actually designed as a desert camo. It was designed as a transitional/ mountainous camo. It is very effective at adapting to the environment, much like multicam. Different light causes the different shades in and patterns inside the camo to show up.
A-TACS FG would probably be even better.
A little fact about me: I love A-TACS. Ever since I saw the original in pics from shot show, I have been in love with this camo. Most local people refer to me as the A-TACS guy.
Oh yeah and lastly, A-TACS is technically a digital camo. So Nickona, it may not be for you.
