U.S. Airsoft Corp was around first but I didn't know when I started U.S. Airsoft.org. Anyway, I know Skip fairly well and have talked with him many times although not recently. USAirsoft.org was more for developing a team of instructors to develop the living history of milsim, honor and safety, and leadership and teamwork.
This is being carried over to a degree with the Moskvaspesnaz team using a Russian theme to attract those more interested in team development than individual coolness.
Individual coolness is what draws people to airsoft.
For guys who aren't in the service, or can't be for whatever reason, airsoft is a way to roleplay for a day or two.
Honestly, it's nice to have teamwork, but I doubt anyone discovers airsoft as a way to work better with others. It's about dressing up and running around with guns, no more.
That "Band of Brothers" stuff you always talk about is found in the military and nowhere else. Anyplace else, it's just called "being buddies." Anyone who tries to tell me otherwise needs to stay in their lane.
