The unit retained most of the Punjab Regiment's uniform, but donned the maroon beret, qualification wings and allied insignias of airborne forces.

Apart from being the oldest infantry battalion in the Indian Army, 15 Punjab also has the proud distinction of being the second highest decorated battalion of the Army, with 22 Battle Honours, one Theatre Honour (Punjab) and numerous gallantry awards.

Thereafter, the battalion sailed to Port Dickson for action in Malaya and Batavia (now Java).
