<entity_2> (<entity_1> – 1 October 1966), Operation Irving (2 October 1966 – 24 October 1966) and <entity_2> II (24 October 1966 – 11 <entity_3>) were related operations with the objective of eliminating People's Army of Vietnam (PAVN) and Viet Cong (VC) influence in <entity_0> on the central coast of <entity_4>. <entity_0>, on the central coast of <entity_4>, was a long-time communist stronghold with the VC, and increasingly the PAVN, controlling most of the rural areas. The 1st Cavalry Division began operations against VC and PAVN forces in <entity_0> shortly after its arrival in <entity_4> in September 1965. <entity_2> was the largest air assault undertaken up until that time in the <entity_5>. During Thayer II, which now had lasted about two and a half months before officially ending on <entity_3>, he had steadily worn down the 3rd Division, driving its 2nd Regiment out of <entity_0> and severely damaging its 18th and 22nd Regiments.
