Mark Berent received his pilot’s wings in September 1953, then flew the F-86 SabreJet and the F-100 Super Sabre in Germany, France, and the U.S. He even caught a ride in the "missile with a man in it", the F-104. In the early ‘60s, the USAF sent him to Arizona State University to get an engineering degree. While there, the Vietnam War became more intense, and he volunteered for duty in Vietnam

In mid-December 1965 he arrived at Bien Hoa Air Base in South Vietnam as a pilot in the 531st Tactical Fighter Squadron (TFS) in the 3rd Tactical Fighter Wing (TFW). He flew over 250 missions and was reassigned back in the States to a desk job at the Space and Missile Systems Organization (SAMSO) in El Segundo, California. Though he was able to fly the T-39 Sabreliner, he was not happy. The war tempo had increased. He made contact with Air Force Personnel and soon found himself at George Air Force Base, Victorville, California, upgrading into the F-4 Phantom.

On the 1st of November, 1968, he signed in to the 497th TFS at Ubon Royal Thai Air Force Base in upcountry Thailand. There he flew over 240 missions both as a Night Owl and as a Wolf Forward Air Controller (FAC).

He wrote the Wings of War series, a five-part series that follows pilot Court Bannister, pilot Toby Parker, and Special Forces officer Wolf Lochert through their successive combat tours in Vietnam. Along the way, we see real events like Johnson and McNamara micro-managing the war, the outrageous abuse of American Pilots held at the Hoa Lo prison, and the claim of an attack on the Russian ship Turkmenestan.
