Foster began his career in law enforcement in 2001, gaining exposure and experience in this field. After spending a few years working in the corporate world and serving as an administrator, director, and teacher, he returned to law enforcement in 2007 and continued in this career until 2019. While as a law enforcement officer, Foster gained several certifications, commendations, and the distinguished Award of Valor. He also served as a member of the S.W.A.T. Team, F.T.O., Traffic Interdiction, Homeland Security T.F., and Firearms Instructor for a Metro Memphis Agency (Desoto CO). In 2012, Foster was promoted to Sergeant, and in 2015, he was hired full-time by a privatized training company. He continued his education and journey to become one of the foremost experts on accessing structures. He was positioned as the lead instructor, directing operations at the range, upon his return from a combat deployment in 2018. Foster also served with the 164th Division of the United States Air Force from 2012 to 2019 in the capacity of Security Forces and fly Away Security Operations (F.A.S.T.). He was promoted to Staff Sgt. and was positioned as Assistant NCIC for F.A.S.T. operations in support of O.I.R. & O.F.S. During this time, he deployed to Europe and the Middle East.
