Who were the Viet Cong What advantages did they have in combat?
For destroying armored vehicles or bunkers, the Vietcong had highly effective rocket propelled grenades and recoilless rifles. Mortars were also available in large numbers and had the advantage of being very easy to transport. Many weapons, including booby traps and mines, were homemade in villages.
Why did Americans fail to win the hearts and minds of the Vietnamese?
The most (in)famous use of a “hearts and minds” campaign by the United States came during Vietnam, and it failed as utterly as any other. Crucial factors were the disorganized nature of the war, local support for the Viet-Cong, and the difficulty in telling apart friend and foe.
