"Trained in combat hand to hand....men who fight by night and day, courage take from the Green Beret"...

(SEALS are pusseys compared to these guys)

He was a bit before my time. I was gifted a sack of his casca books and really enjoyed them as a young teen.

The writer Robin Moore, author of the novel The Green Berets, which became a 1968 movie, The Green Berets, featuring John Wayne, helped Sadler with lyrics and with getting a recording contract with RCA Victor Records. Sadler moved to Guatemala City in 1984. He continued to write and publish his Casca books, produced a never-released self-defense video, and provided free medical treatment in rural villages. On September 7, 1988, Sadler was shot in the head while sitting in a cab in Guatemala City. Witnesses said he accidentally shot himself, but his friends and family believed he was shot by a robber or an assassin. He was flown to the United States by friends in a private jet paid for by Soldier of Fortune magazine publisher Bob Brown.
After being moved from multiple VA hospitals and eventually to the VA Hospital in Murfreesboro, Tennessee, in February 1989, he never recovered from his injury. He died there of cardiac arrest on November 5, 1989, four days after his 49th birthday.
