Its role is to protect and defend the capital city area with other additional tasks, such as to support the local law enforcement and civil authorities (by request).
On 29 September 1945, allied forces (with Netherlands Indies Civil Administration personnel attached) under the command of Lt. Gen. Sir Philip Christison landed from HMS Cumberland in Tanjung Priok Harbor to disarm Japanese troops and to liberate prisoners of war.
On 24 September 1949, the Dutch government recognised Indonesia's Independence, one of the first actions of which was the signing of documents for the transfer of power in the Jakarta Raya area from Comando Batavia En Ommelanden of the Dutch to Basis Comando Jakarta Raya of Indonesia, under supervision of Komisi Tiga Negara (KTN).
After that, on 19 January 1960, at 9:00 am in Lapangan Banteng, the Chief of Staff of the Army, Lt. Gen. Abdul Haris Nasution, appointed Col.(inf) Umar Wirahadikusumah as the first Commander of Kodam V/Jaya.
Col. Wirahadikusumah was spared from any action due to pressure from Maj Gen Suharto, then commander of Kostrad, for him to prevent having to join the rebel forces in his area of operations.
