The original armoured car was scrapped before the outbreak of World War II, but the remaining four all played an important role in the Battle for Hong Kong in December 1941 .

1941 - Hong Kong captured by the Japanese
The volunteers, renamed the Hong Kong Volunteer Defence Corps, met their severest test in the bitter fighting that took place in the crucial weeks before the fall of Hong Kong on Christmas Day. Out of the mobilised strength of 2 200 of all ranks, 289 were listed either as missing or killed, and many others became prisoners of war. Some, however, made their way into China where the British Army Aid Group was formed to assist the Chinese Government in the struggle against the Japanese. A further group made its way to Burma where it joined the famed Chindits under General Orde Wingate. The services of the defence corps were later recognised by the award of 19 decorations and 18 mentions in despatches for gallantry and good service.

The naval unit was phased out and in 1970 the Royal Hong Kong Defence Force was itself disbanded-the two remaining member units, the Hong Kong Regiment and the Hong Kong Auxiliary Air Force, officially becoming separate entities. At the same time, both were granted the 'Royal' title by Queen Elizabeth, and the words The Volunteers' were incorporated into the Hong Kong Regiment's title.

1971
Partly because the modern-day regiment had, since 1961, been organized and trained as a light reconnaissance unit and partly because the original Hong Kong Defence Force no longer existed in its old form, it was decided that the regiment should have new colours. So, with the approval of the Queen, the single guidon of a reconnaissance unit was presented in 1971.
