On May 4, 1991, the Headquarters of the 1st Infantry (TABAK) Divisio was named in honor of Major Cesar L. Sang-an who died defending the country’s sovereignty against a superior number of MNLF forces of Barangay Malaning, Labangan, Zamboanga del Sur on 23 March 1973. Sang-an was a brilliant Scout Ranger officer and a courageous fighter.
Though twice wounded, he directed and covered his men until he was killed. This heroism earned him the award of the Distinguished Conduct Star (Posthumous) from the Armed Forces of the Philippines. He was born on 3 November 1926 in Kinogitan, Misamis Oriental.
The Camp is located on a 422.81 hectare military reservation surrounding Barangay Upper Pulacan, in Labangan, Zamboanga del Sur. This reservation was taken over by the Division from Army Reserve Command (ARESCOM) on 16 August 1987.
From being rugged and mountainous, the Camp was slowly developed into a sprawling and thriving military camp with the help of the 545th Engineer Battalion, 52nd Engineering Brigade, Philippine Army.
