The only active support/player area for Decisive Action that I am aware of is here. The members tend to be mainly serving or ex forces members. Decisive Action and for that matter most of the other sims supported here are niche market sims. They generally appeal to gamers who are seeking sims that truely mimic military planning with great detail and depth. Hence the reason that if you want to buy HPS or Shrapnel games in the UK you either have to buy them direct from the U.S. or Strategic Plus who are the sole suppliers here in the U.K.
