Without artillery support, without reinforcements, they turned a suicide mission into a success. Battered and depleted by the Vietcong guerrillas' sadistic style of warfare, allied intelligence unleashed their secret weapon: an experimental Army Special Forces unit that the government brass didn't know existed. They used the enemy's booby-trapped trails and grenade-in-you-backpack tactics in a sprawling mass of jungle. James C. Donahue, a member of Operation Blackjack-31, chronicles the treacherous trek through War Zone D by thirteen handpicked Green Berets who infiltrated the VC's "secret zone" and proved just how far determination can go. "Donahue has captured the sight, scent, and emotions of the ultimate unconventional soldier in this highly accurate account of the guerilla fighter in Vietnam." -- D avid Christian, Past National Commander, Legion of Valor, Author of Victor Six "Jim Donahue tells it like it was. Mobile Guerilla Force is an outstanding book. A must read for Vietnam vets." --Allen "Gunner" Kent, Past Commander in Chief, Veterans of Foreign Wars James C.
