Kevin "Dauber" Lacz (born December 26, 1981) is a United States Navy SEAL veteran who served two tours in the Iraq War. His platoon's 2006 deployment to Ramadi has been discussed in several books, including Dick Couch's The Sheriff of Ramadi, Jim DeFelice's Code Name: Johnny Walker, Jocko Willink and Leif Babin's Extreme Ownership: How U.S. Navy Seals Lead and Win and Chris Kyle's New York Times best-selling autobiography, American Sniper. Lacz's presence in the book led to his involvement in the production of and eventual casting in the Clint Eastwood-directed Oscar-winning biopic of the same name (starring Bradley Cooper).
