Following the lead of the US Army, in 1960 the Australian Army had replaced its former "triangular" divisional structure of three infantry battalions under a brigade headquarters, with a "pentropic" organisation consisting of five larger battalions without a brigade layer between division and battalion headquarters. This had the effect of reducing the total number of Australian battalions, while increasing their individual strength. Wilton was unhappy with the pentropic structure, reasoning that the number of battalions, rather than their relative strength, was the overriding factor when considering potential overseas deployments. The US had in any event abandoned the system in June 1961. In October 1964, Wilton commissioned a review that ultimately recommended a return to the triangular formation. In the meantime, as a response to the Indonesia–Malaysia "Konfrontasi", the Australian government reintroduced conscription, which Wilton fought until convinced that the government was not going to improve pay and conditions sufficiently to attract by any other means the recruits needed to meet overseas commitments. Wilton was keen to mitigate any prejudices the national servicemen might have against the regular soldiery, and vice versa; when he found a memo from an Army committee asserting that "it must be recognised that the NS man was likely to be a reluctant soldier", he wrote on it "This assumption not justified". In February–March 1965, following a request from the Malaysian government, Australia despatched 1 Squadron, Special Air Service Regiment, and 3rd Battalion, Royal Australian Regiment, to Borneo—a commitment Wilton felt able to recommend as a result of the recent decisions to increase the Army's personnel and battalion numbers.
