So I just recently bought ARMA2 and ARMA:OA and I barely played any of them when I saw this mod and decided to play it. Well I looked at all the beginers guides etc. but there isnt any tutorials on how to use gear etc. I know how to do the basics ie: Go prone, crouch, open gear bag, change weapons, etc. but I still have yet to figure out how to apply bandages and use my gear etc. Any help or redirection to a tutorial on how to do all this would be much appreciated. Thanks!
