Before Willie Nelson became one of country music's biggest names, he served in the United States Air Force. After graduating from high school in 1950, Willie enlisted and went through basic training at Lackland Air Force Base in San Antonio, Texas. He also trained at Sheppard Air Force Base in Wichita Falls and spent time stationed in Biloxi, Mississippi. Unfortunately, his military career was cut short when back problems led to a medical discharge after about nine months. Although his time in uniform was brief, Willie has never forgotten those who served. Over the years, he has supported veterans' organizations and spoken out about the need for better medical care and assistance for homeless veterans. After leaving the Air Force, Willie worked several jobs, including as a radio disc jockey, while continuing to write songs and perform. He eventually gave us country classics like "Crazy," made famous by Patsy Cline, "Hello Walls," recorded by Faron Young, and his own unforgettable hits, "On the Road Again," "Always on My Mind," and "Blue Eyes Crying in the Rain." He also joined Johnny Cash, Waylon Jennings, and Kris Kristofferson to form The Highwaymen. With his unmistakable voice, braided hair, and trusty guitar Trigger, Willie became a country music legend. Many folks know his songs by heart, but not everyone knows that Willie Nelson also wore the uniform of the United States Air Force.
