During his service career, Isom won four Bronze Star Medals, including two with distinction for valor, two Combat Action Ribbons, and a Presidential Unity Citation, Task and Purpose reported.

Most recently, Isom has served as the Command Senior Enlisted Leader for US Indo-Pacific Command.

Isom joined the Navy in 1987, inspired by his Korean War Army veteran father and a love of the ocean that he discovered while surfing off the coast of his native North Carolina, he revealed in an interview in 2022.

The decorated SEAL revealed that he was promoted to the rank of Chief Petty Officer around the time of September 11th, 2001, and was soon deployed to the Middle East.

After losing “teammates” while fighting in Afghanistan in Iraq, Isom said he learned, “the key role of leaders and caring for people and developing other leaders,” according to that interview.

Master Chief Isom is replacing current SEAC Troy E. Black, the DoD said in the release.
