No Easy Day is a best-selling book that recounts the mission that killed Osama bin Laden. It's come under a great deal of controversy as its author, Matt Bissonnette (under pen name Mark Owen), did not seek Department of Defense approval before releasing the book. The DoD claims that the book reveals potentially classified information. The Pentagon has threatened legal action.
Apparently, Bissonnette has also consulted on Medal of Honor: Warfighter, the next military shooter from Electronic Arts. And as with No Easy Day, he did not receive authorization to do so.
When asked by The LA Times about their involvement with Bissonnette, an EA spokesperson said that "EA did not directly remunerate Mark Owen for his input on Medal of Honor Warfighter." True, because the publisher paid Silent R, a company which Bissonnette worked with, to "produce a series of promotional videos on authentic combat experiences in the war on terror."
While it's unlikely the Medal of Honor games (and any promotional materials for it) would reveal any classified information, Bissonnette's actions certainly seem unsavory. As one person noted on Kotaku, "This guy, very simply, sought to profit from his experiences as an operator." But, another commenter points out that "to think that terrorist groups would seek intel via a video game is ridiculous."
