Executive producers Shawn Ryan (The Shield) and Pulitzer prize-winning playwright David Mamet bring riveting, action-packed, pulse-pounding TV drama to DVD.

They are The Unit, a covert Special Forces team operating outside the usual military chain of command, risking their lives on undercover missions at home and abroad. Whether stateside or aboard, these heroes are on the frontlines protecting U.S. citizens and foreigners alike, slipping in under the radar and risking their lives to save the day then leaving just as quietly without any well-deserved credit or thanks.

Now you can enjoy all four seasons of this groundbreaking show, for the first time ever in one DVD set.
