Military Strategies in Vietnam

Attrition and Search and Destroy Missions

  • The U.S. military initially employed a strategy of attrition, seeking to inflict heavy casualties on the enemy through superior firepower and technology

    • This strategy sought to "Vietnamize" the war, allowing the South Vietnamese to take the lead in fighting while the U.S. provided support and training
    • However, the South Vietnamese military often lacked the motivation, leadership, and capabilities to effectively combat the North Vietnamese and Viet Cong
  • Despite technological and numerical superiority, the U.S. military struggled to adapt to the guerrilla warfare tactics employed by the Viet Cong and North Vietnamese forces
    • The enemy used hit-and-run tactics, ambushes, and blended in with the civilian population, making it difficult for U.S. forces to engage them directly
