Corporal Sylvester Ellis was a member of 3rd Battalion, 22nd Infantry Charlie Company. C/3/22 arrived in Vietnam in 1966 and was released in 1971. They were apart of the 25th Division and known as the Tropic Lightning Division. Their unofficial motto is "Regulars, by God" which originated from General Rials in 1814. After the war ended, they created a nonprofit organization in dedication to members both lost and still alive. The name of the organization is C/3/22 Infantry Association and is opened to all veterans of the Vietnam War. They also host reunions every two years, with one occurring in Branson in 2019.
