Britain's 2nd King Edward VII's Own Gurkha Rifles was based in Brunei in the 1980s. The regiment's two battalions (each with approx. 650-800 soldiers) alternated between Malaya, Borneo, Brunei and Hong Kong.
ATL - after serving mostly in warmer climates, it's determined that the Gurkhas would benefit from cold weather training, in case they're needed in NATO ops in Norway and other British led areas in ETO. Not wanting to take on great expense, seeing that the full winter hasn't arrived in the south, it's decided to send them to the Falklands for six months of training, including live fire training, outdoor cold weather survival, etc.
Thus, a single company of 250 Gurkhas are sent to the Falklands via Chile, leaving Brunei in early March 1982, arriving by vessel March 25, 1982, along with their rifles, grenades, light mgs, winter kit (tents, coats, boots, etc.) and their Kurkis. The company will be subordinate to Major Mike Norman during their training period.
By the early morning of March 27 the Gurkhas have moved into Moody Barracks, unpacked their kit and began preparing for Major Norman's inspection and commencement of winter combat training. Norman's force of 68 Royal Marines welcome the newcomers and the shared respect is evident. Spies on the islands report back to Argentina of the arrival of the troops, but the arrival of 250 small sized men from the tropics are not considered much of a problem.
April 3rd, Argentina invades South Georgia, Major Norman meets with the Gurkha commander and orders his men to prepare for trouble.
Major Norman's got 68 Royal Marines, 11 sailors and now 250 Gurkhas, the latter of which you know will not surrender, their motto being Better to die than live a coward.
Does this change anything? You've still got thousands of Argentinean troops about to arrive! If we changed it to two companies, totaling 500 Gurkhas, would the Argies still come?
