春節攻勢
In 1968, Kizirian uncovered the Tet Offensive, a military campaign that was launched on January 30, 1968 by forces of the Viet Cong and North Vietnam, after studying more than 400 intelligence reports and subsequently briefing General Creighton Adams. Kizirian's prediction of the 1968 Tet Offensive is considered one of Kizirian's greatest achievements of the war effort.
