[4] At the end of the Indo-Pakistan War in 1965, a new battalion called the Lucky Tigers of the 7th East Bengal Regiment was created.

The structure and formation of the Bangladesh Forces during the Independence War of 1971 was determined at the Sector Commander's Conference that was held from 11 to 17 July 1971.

Lieutenant Colonel M. A. Rab was appointed as the Chief of Army Staff and Squadron Leader M. Hamidullah Khan, was appointed Bangladesh Military Representative to coordinate guerilla training at the largest training camp of the war effort at Chakulia, Bihar, India.

These battalions were formed during May~June 1971 at Teldhala village of Tura, Meghalaya, in 1971 by Major Ziaur Rahman.

These three battalions principally constituted the backbone of Bangladesh Forces Sector 11, later commanded for a brief stint (24 days) by Major Abu Taher and subsequently by Squadron Leader M. Hamidullah Khan from 3 November until 14 February.

The regiment also aids the civilian government when called on and contributes regularly to Bangladesh's peacekeeping commitments overseas.
