The branches of the United States military have had a strong presence in video games since the dawn of the medium, with appearances in genres from primitive arcade shooters to real-time strategy, first-person shooters, scrolling shooters, to the occasional beat-'em-ups. Few of these titles have actually had official military involvement or input, but recently that has begun to change. Not only have the different branches sponsored "official" games, but they have also used serious games to provide training for their soldiers. So the recent news that the US Army has decided to invest $50 million into video game development was not much of a surprise to the industry. After all, the Army has realized that video games are immensely useful tools, both for capturing the public's interest, as well as training soldiers in the art of war.
