Indonesian Army infantry battalions

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. Indonesian military units are commonly referred to by compound words. Infantry battalions are routinely called as Yonifs which is a portmanteau from "batalyon infanteri" ('infantry battalion'). They are also commonly referred to by their battalion nicknames, for example: 511th Infantry Battalion - "Dibyatama Yudha".
