This Navy SEAL unit was 'the most hard luck platoon' to fight in Vietnam
The last time a Navy SEAL team used x-ray as an identifier was when the unit deployed to the Mekong Delta area in late 1970. Lt. Cmdr. Mike Walsh was a SEAL in Vietnam during the war. He was wounded at Ben Tre while serving with SEAL Platoon X-Ray in February 1971. In an interview with Vietnam Magazine, Walsh called X-Ray "the most hard-luck SEAL platoon to serve in Vietnam."
