MM we'll all be "super trouper"s in no time!
To be honest I like the idea of the patch, not so much the wrist band I never really look at them. I'm sure something fairly cryptic would be good as it means that people would ask what its all about. I guess it's hard to balance being visible with being tacticool.
Something like the "hit takers" one down at the EAG sites.
Your ideas are great and I am happy to be involved with it if it ever comes good. By the sounds of it you are thinking along the lines of GZ but with a charity focus. H4H are very high profile but their methods can be questionable. The British legion are a charity I support more regularly, but its your baby, if you are set on H4H then its ok.
Perhaps a little fun with a forces acronym might be nice. Or I'd tried AirSOFT = Airsoft Supporters Of Forces T(this is where I ran out of ideas). Or something like SNAFU = Supporters of Nominated Altruistic Forces U(again with the lack of ideas) or change the U to an O and it could be Organisations, then when people go "haha you noob you got that wrong SNAFO should end with a U" and you can respond with what it means.
