Pentropic organisation

[2] The key element of the Pentropic organisation was the reorganisation of divisions into five combined arms battle groups.

The other regular infantry battalion remained on the previous tropical establishment as it formed part of the 28th Commonwealth Brigade in Malaysia.

It was believed that these new weapons would further improve the Army's combat power and the ability of sub-units to operate independently.

[3] The experience gained from exercises and changes in Australia's strategic environment led to the decision to move away from the Pentropic organisation in 1964.

During the early 1960s small counter-insurgency wars broke out in South East Asia, and the large Pentropic infantry battalions were ill-suited to these operations.

Then Brigadier Reg Pollard in Korea, 1953. As Chief of the General Staff, Pollard oversaw the restructure of the Australian Army along pentropic lines. [ 1 ]
Then Colonel John Wilton in Morotai, September 1945. As Chief of the General Staff, Wilton later commissioned a review that ultimately recommended a return to the triangular formation. [ 7 ]
