In 1921–22, a major reorganization was undertaken in the British Indian Army leading to the formation of infantry groups of four to six battalions. Among these was the 16th Punjab Regiment, formed by grouping the 33rd Punjabis with the
30th,
31st and
46th Punjabis, and the
9th Bhopal Infantry. The battalion's new designation was 3rd Battalion 16th Punjab Regiment. During the
Second World War, the battalion fought in the
Malayan Campaign and was taken prisoner by the Japanese on
Singapore Island following the British surrender on 15 February 1942. It was re-raised in 1946. In 1947, the 16th Punjab Regiment was allocated to Pakistan Army. In 1956, it was merged with the
1st,
14th and
15th Punjab Regiments to form one large
Punjab Regiment, and 3/16th Punjab was redesignated as 15 Punjab. In 1948, the battalion fought in the war with India in
Kashmir, while during the 1965 Indo-Pakistan War, it fought at the
Rann of Kutch and Chhamb-Jaurian. In 1971, it served in
Lahore Sector. ==Genealogy==
