Advisory team 90

• Advisory Team 90 (AT 90) was part of the U.S. Military Assistance Command, Vietnam (MACV), responsible for advising the Army of the Republic of Vietnam (ARVN) forces in Quang Tin Province. • AT 90 operated primarily in the I Corps Tactical Zone, focusing on areas such as Tam Ky, the provincial capital, and the surrounding rural districts during the Vietnam War. • The team played a critical role during the 1968 Tet Offensive, helping coordinate ARVN and American responses to major attacks on Tam Ky and nearby installations. • Members of AT 90 frequently accompanied ARVN units on combat operations, facing significant risks from ambushes, booby traps, and direct enemy engagement. • One notable story involves AT 90’s quick actions in early 1972 during the North Vietnamese Easter Offensive, when advisors helped organize an emergency defense of Tam Ky against a large-scale assault. • The team included specialists in infantry, artillery, intelligence, logistics, and communications, ensuring ARVN units received comprehensive support and training. • Several AT 90 members were awarded valor decorations, such as the Silver Star and Bronze Star, for heroism under fire while advising and fighting alongside Vietnamese troops. • AT 90 also played a humanitarian role, assisting with medical care, refugee relief, and reconstruction projects in war-torn Quang Tin Province. • The team’s compound in Tam Ky was a frequent target for enemy rocket and mortar attacks, requiring constant vigilance and rapid reaction capabilities. • Advisory Team 90’s legacy is preserved through the memories of its veterans and their participation in reunions, oral histories, and military history projects dedicated to the Vietnam War.
