The National Navy UDT-SEAL Museum in Fort Pierce, Florida, eulogized Marcinko in a Facebook post, saying he “played a very unique part in SEAL history, leaving a legacy like no other.” He led  SEAL Team 6 from August 1980 to July 1983.

In addition to his military career, Marcinko wrote several books including an autobiography titled “Rogue Warrior.”
