I didn't know anything about airsoft until about ten minutes ago, when I came across this local business:
http://www.battlesim.com/
Unlike paintball, those involved in airsoft are in it as much for the simulation or reenactment part as anything else. If you check out the site above, you'll see the extent to which the participants get into their roles. This is apparently particularly popular in Asia, where it first began. In fact, now that I think about it, there's a scene with someone shooting an airsoft gun in the film Lost in Translation.
Battlesim is a local firm if you're in the area and interested. They are doing a re-enactment of the Battle of the Bulge at the end of this month in Duvall, northeast of Seattle.
