This may sound like a 'heard it from A, who heard it from B, who told them that C knew this guy D'... I was in the Marine Corps and worked with people who knew Dick Marcinko. It was well known the SEAL community that all of his early stories are based in fact, with sensitive details changed (names, countries, time of year, conversations created), and that they did not happen to him, but some of his team members. Either way, with the well known John Weisman on assist, the Rogue Warrior series moves along as well as any Jason Bourne novel. Give them a try!
The Rogue Warrior has come to Moscow to investigate the assassination of Paul Mahon, U.S. defense attache' in Russia. Marcinko knows who killed him, Andrei Yudin, a godfather in the Russian Mafia and he wants to know why. Instead, he finds a cabal of corrupt, mob-linked Russian politicians. The revelation gets him yanked back to Washington where orders come down to disband his elite team of SEALS.
