Very cool idea mate
Might provoke a few politically induced fires around certain camps but as long as you don't insult too many people this has great potential.
Oh and don't worry about insulting the British (we are used too it :) ) loving the Mel Gibson comments :D
Don't know if you have already answered this but what kind of British kit will you be using (don't see much on the kit list) ? Just the standard Bluefor stuff? Or are you going to make your own/borrow existing models of contemporary British gear (SA-80's, jackals) ?
Also, how are the missions going to run? More linear story with strict objectives? Or more open world blow up what you can get to kind of thing.
Thanks and good work
