One of the exhibitors in this year's air show was featured in a page one story in the Wall Street Journal. The article says visitors to the 19,500 square-foot exhibit experience riding in a Humvee or a Blackhawk helicopter while using fake firearms to hunt down enemies.

"Players file into an air-conditioned trailer, filled with computers and Xbox 360 consoles, where they wait to be briefed. Then Staff Sgt. John Harper explains the mission: Genocidal indigenous forces are attacking international aid workers. It's up to the players to protect them.

"Participants enter a dark, inflatable dome. They climb into one of six modified Humvees or two Black Hawk helicopters. Each vehicle, mounted with fake M-249 Squad Automatic Weapons and M-4 rifles, faces three huge screens where the videogame is projected.

"Players fire air-pressured guns, meant to mimic the recoil and kickback of real ones. The ethnicity of the bad guys they shoot at is ambiguous. The rat-a-tat-tat of gunfire blares from the game's speakers and the Humvees shake from the simulated blasts of roadside bombs. Some participants hoot and holler. Despite the nature of the game, there is no blood or guts on screen.

"Scores are higher if players only shoot people in uniform; they lose points for firing indiscriminately or at noncombatants."
