In 1968 the dual operational requirements to conduct counterinsurgency and main force operations simultaneously also challenged the way 1ALSG provided logistic support to 1ATF. In 1966, HQ AFV and 1ALSG had constructed a logistic system to provide support to 1ATF centred on a static base at Nui Dat, with 1ATF conducting operations within Phuoc Tuy province. However, the events of the impending VC Tet Offensive in January to February 1968 would bring a radical change in how 1ATF operated, requiring 1ALSG to provide support not only to Nui Dat but also to a series of air-mobile operations and associated fire support bases (FSBs) established outside the province.
