15th Infantry Brigade (Indonesia)

The brigade was initially formed by order of Kodam Siliwangi's commander on 15 December 1962 (though the unit celebrates its anniversary as 31 October 1962).^[1][2] It initially received the nickname "Tirtayasa" and was provisionally based in Sukabumi. Its initial composition contained the brigade headquarters along with the 310th, 320th, and 327th Infantry Battalions. Its nickname was changed to Kujang II in 1970, following the absorption of Siliwangi's 17th Infantry Brigade/Kujang to Kostrad.^[1]

In 1963, the brigade took part in Operation Masohi in Seram, Maluku, to wipe out the remnants of the Republic of South Maluku (RMS). The brigade was credited with the capture of RMS President Chris Soumokil and the chief of staff of its armed forces Sopamena, both in December 1963. During the Indonesia–Malaysia Confrontation, the 15th Brigade was stationed in Riau, and then it took part in purges against the Indonesian Communist Party mostly in Jakarta and West Java.^[1]

As of 2025, the brigade is based in Cimahi, West Java.^[3] Some of its units, such as the 310th Battalion, has been deployed to the Indonesia–Papua New Guinea border.^[2]
