Despite the namesake, Camp Alfred Vail was at United States Army base Fort Monmouth in New Jersey and was a training center for the signal corps. The United States Signal Corps was founded in 1860 and has played integral roles in military communication, technologies, and logistics since the Civil War. Fort Monmouth was closed in September of 2011 and is now a historic district.
