Pembela Tanah Air

PETA (Indonesian: Pembela Tanah Air - Defenders of the Homeland) or Kyōdo Bōei Giyūgun (郷土防衛義勇軍) was an Indonesian volunteer army established on 3 October 1943 in Indonesia by the occupying Japanese. The Japanese intended PETA to assist their forces oppose a possible invasion by the Allies. By the end of the war, there were a total of 69 battalions (daidan) in Java (around 37,000 men) and Sumatra (approximately 20,000 men). On 17 August 1945, the day after the Indonesian Declaration of Independence, the Japanese ordered the PETA daidan to surrender and hand over their weapons, which most of them did. The Indonesian Republic's newly declared President, Sukarno, supported the dissolution rather than turn the organisation into a national army as he feared allegations of collaboration had he allowed a Japanese-created militia to continue in existence.

During the Indonesian National Revolution, former PETA officers and troops, such as Suharto and Sudirman, formed the core of the fledgling Indonesia armed forces.
