The base was first established in 1965 by the 1st Cavalry Division for the Battle of Ia Drang, just south of QL-19 and approximately 24 km southwest of Pleiku.^[1] The base was originally named after SSGT Arlen Tuttle, an Engineer from the 8th Engineer Battalion, 1st Cavalry Division who was killed in action on 5 November 1965.^[2]
