DVice.com fulfills that long-held suspicion (in some circles) about videogames and military recruiting with a report on new games actually produced by the Pentagon:
ACTUV Tactics is based on a real DARPA program to develop new ways to hunt down enemy submarines, but the really cool part is that your tactics and results can be sent directly to DARPA for analysis. DARPA thinks that there must be some really clever kids out there who could come up with some sub hunting tactics they never thought of, and they plan to use crowdsourcing with this game to learn them.
