There, he joined the GITMO Judo Kai, and, because of the various martial arts disciplines taught there at the time, Sensei Mantack recommended the name be changed to the Guantanamo Bay Self Defense Club.
His recommendation was adopted, and the name changed. Sensei Mantack became the assistant instructor to Grandmaster Ramon Bodine, a Cuban National, and Chief Martial Arts instructor at the base. Additionally, instructing at the club, was Sensei Robert Price, a first class petty officer in the U.S. navy, who held the rank of Sandan, a third degree black belt in Judo. Grandmaster Bodine held the rank of (Nanadan/kyoshi) a seventh degree black belt in both Tae-Kwon-Do, and Shorin-Ryu, a (Godan) fifth degree black belt in Kenpo, and a (Yondan) fourth degree black belt in Judo.

Grandmaster Bodine also promoted Master Mantack to the rank of (Sandan); a third degree black belt in Judo.

On February 15, 1974, after a three-hour test, Grandmaster Albert Darrenburg, recommended Master Mantack for the rank of (Rokudan), the six degree black belt, in Okinawan Shorin-Ryu. On June 15, 1974, the governing body approved the recommendation, and Sensei Mantack was promoted to the rank of (Rukudan), a sixth degree black belt, and awarded the title of Shihan. Grandmaster Darrenburg also reaffirmed Mantack’s rank as (Sandan), a third-degree black belt in Kenpo Karate.
Shihan Mantack, along with other students from the Guantanamo Bay Self Defense Club, would frequently travel to other U.S. Naval Bases, including Lapon Bridge, in West Virginia, and Rosey Roads, in Ceiba, Puerto Rico, to compete in Martial Arts tournaments, and to conduct demonstrations, and seminars.
In 1975, Shihan Mantack left Guantanamo Bay, Cuba, and migrated to the United States, and, through his various contacts at Guantanamo Bay, and on the recommendation of the base commander, he procured a contract with the naval dependent recreational service in San Diego, and began teaching at several military recreational centers in San Diego county.

Between 1976 and 1991, Shihan Mantack, along with students from all three martial arts schools, participated in numerous tournaments, and competitions throughout California, Nevada, Arizona, and Mexico. However, during the seventies, the eighties and into the early nineties, students from the United Karate Federation (UKF) practically dominated the tournament circuits, as a result, Mantack decided to resume his training in Kenpo, under Master Orned (Chicken) Gabriel, an eight degree black belt, under the late Grand Master Richard (Dick) Willett.
During those early years, Mantack competed against many formidable opponents; such as Reynaldo Leal, Pete Salas, Herb Hoffmann, Crane Ponder, and Tony Pablo, just to name a few. On August 17, 1994, Shihan Mantack was honored, by being awarded his seventh degree black belt (Shichidan) certificate, and promoted to the rank of Master, by Grand Master Albert Darrenburg.
