This is a joke right? You guys can't be seriously inviting the army to PAX.
Do you honestly think that they're going to show up just to promote their game (obvious recruitment tool BTW), and go home? Hell no! They're going to have recruiters covering the halls and the game rooms trying to get people to sign up, adding tension and aggrivation to an event that's supposed to be a fun, sleepless, 3-day weekend of gaming, music, and general dork insanity.
Please reconsider. Take a page out of the book of the PTSA's in Seattle high schools and keep the army out of PAX.
