One word sums up Garrison Chaplain Lt. Col. Charles Lahmonâs approach to his ministry: service. Lahmon has become the Garrison chaplain after serving for three years as the Aviation and Missile Command chaplain. Though he has been serving as an Army chaplain for about two decades now, Army service wasnât always his ultimate goal. A native of Mount Vernon, Ohio, Lahmon initially joined the Army out of high school in 1988 with the intention of joining an Army band. Not only would the Army help him pay for college, but it would give him the opportunity to fulfill his dream of becoming a professional musician.
