 On 23 September 1950 , 3 RAR embarked for Korea , concentrating at Pusan on 28 September . There it joined the British 27th Infantry Brigade , a garrison formation hurriedly committed from Hong Kong by the British government as the situation deteriorated around the Pusan Perimeter in late August to bolster the US Eighth Army under Lieutenant General Walton Walker . Commanded by Brigadier Basil Coad , the brigade was renamed the 27th British Commonwealth Brigade and consisted of the 1st Battalion , Argyll and Sutherland Highland Regiment ( 1 ASHR ) , the 1st Battalion , Middlesex Regiment ( 1 MR ) and 3 RAR . Under @-@ strength , the two British battalions had each mustered just 600 men of all ranks , while the brigade was also short on transport and heavy equipment , and had no integral artillery support , for which it would rely entirely on the Americans until the 16th Field Regiment , Royal New Zealand Artillery arrived in January 1951 . As such , with a strength of nearly 1 @,@ 000 men , the addition of 3 RAR gave the brigade increased tactical weight as well as expediently allowing the Australians to work within a familiar organisational environment , rather than being attached to a US formation .
