Kevin Lacz is not a Navy SEAL. He completed his Navy enlistment about six years ago, which makes him a former SEAL, but he still looks like he could swim a mile in full combat gear. That, I assume, has something to do with the reason he became an elite special operator in the first place: Lacz is extremely competitive. He’ll be the first to admit it. In fact, throughout his new memoir, “The Last Punisher,” which was co-authored by his wife, Lindsey, and writer Ethan Rocke, Lacz constantly reminds us that a love of competition is the one quality all Navy SEALs share. And it’s not just limited to training. In Lacz’s telling, a SEAL’s drive to be the best of the best is most apparent on the battlefield, where combat is sought after and kills are tallied like points in a dart game.
