The Indonesian Army has formed a large number of infantry battalions since it was formed from provisional militias during the Indonesian National Revolution against the Dutch colonial rule, 1945–1949. Today, the International Institute for Strategic Studies' Military Balance 2007 lists the Army with 2 brigades (6 battalions) plus 60 other battalions in the KODAMs, or Military Regional Commands, and nine battalions in KOSTRAD, the Army Strategic Reserve Command. There are also around nine airborne battalions.
