The 'Newsroom' alum will play a high-level operations officer in the 10-episode second season.

Olivia Munn is enlisting with History for a major new role.

The Newsroom actress has joined the A+E net's military drama Six as a series regular for season two, The Hollywood Reporter has learned.

Munn will play Gina, a ruthless and smart CIA operative who rose from being a CIA shooter to a high-level operations officer.

From executive producers Harvey and Bob Weinstein, Six is inspired by the real missions of Navy SEAL Team Six, the unit best known for killing Osama Bin Laden. The drama, which debuted in January as History's second original scripted series, explores the emotional truths of what it means to be in SEAL Team Six, their complex personal lives and the life-and-death decisions that protect American interests.

Munn is set to appear in all 10 episodes of season two, which is set to begin production this month in Vancouver. She joins fellow new season two addition Eric Ladin (The Killing), who will play Trevor, an experienced SEAL who joins the team and disrupts the status quo.

Six's ensemble includes Barry Sloane, Kyle Schmid, Juan Pablo Raba, Edwin Hodge, Brianne Davis, Nadine Velazquez, Dominic Adams, Jaylen Moore and Lindsley Register.

After getting her start on the small screen on Attack of the Show, The Daily Show and HBO's The Newsroom, Munn has moved her focus to film in recent years with roles in X-Men: Apocalypse, Office Christmas Party and the forthcoming Predator remake. She is also a best-selling author, having written the 2010 entry Suck It, Wonder Woman: The Misadventures of a Hollywood Geek. Munn is repped by CAA and Atlas Artists.

Six was created and is written by Oscar nominee William Broyles (Cast Away, Apollo 13, Jarhead) and his son, David Broyles, a military special operations veteran. The two executive produce with the Weinstein brothers, Bruce C. McKenna, Alfredo Barrios, Jr., George W. Perkins, David Glasser, Nicolas Chartier, Meryl Poster and Barry Jossen. Retired U.S. Navy SEAL Mitchell Hall (Zero Dark Thirty) serves as the series’ technical advisor and producer. Arturo Interian serves as the executive in charge of production for History.

The series is produced by A+E Studios in association with Weinstein Television. A+E Networks handles worldwide distribution rights.
