 As part of these changes , in July 1960 the 27th Battalion was amalgamated with the 43rd / 48th Battalion ( Hindmarsh Regiment ) and 10th Battalion ( The Adelaide Rifles ) to form the Pentropic 1st Battalion , Royal South Australian Regiment ( 1 RSAR ) , with the 27th Battalion 's personnel forming ' A ' and ' B ' Companies within this organisation . The 16 battle honours awarded to the 2nd AIF 's 2 / 27th Battalion , which had served in North Africa , Syria , and New Guinea with the 7th Division were entrusted to the battalion in 1961 , through the promulgation of Army Order 135 . In 1965 , the Australian Army 's experiment with the Pentropic structure was abandoned and the CMF was once again reorganised with many of the Pentropic battalions being split once again to form additional battalions . On 1 July 1965 , 1 RSAR was split and the 10th , 27th and 43rd Battalions were reformed in their own right as battalions of the Royal South Australia Regiment . On 29 November 1987 , the 10th and 27th Battalions were linked to form the 10th / 27th Battalion , Royal South Australia Regiment ( 10 / 27 RSAR ) . This unit continues to exist to this day , maintaining the battle honours and traditions of its predecessor units .
