Spectre of War - The Airmen Series, #19

As the American military continues its withdrawal from Vietnam, the CIA steps up its covert operations and training of Cambodian troops. New weapons are developed to stop the communists. With its powerful cannons, the Spectre gunship proves to be a deadly force capable of destroying any weapon or vehicle the communists can field and ensures that reinforced bunkers are no longer a safe haven. Realizing the survival of their country will soon be in their hands, ARVN troops attack the NVA and Viet Cong all over South Vietnam with surprisingly good results.
It seems there is hope. When Cambodian military operations fail, the ARVN attempt to cut off enemy supply lines in Cambodia but do little to slow the flow of weapons and ammunition into South Vietnam. Refusing to give up no matter the odds, Granier and Coyle do their best to stop the communist surge they know is coming. As the Vietnam War approaches its final phase, the story reveals the brutality mankind can inflict on its own.
