The two sides involved in World War I were the Allies and the Central Powers. Both sides had basically the same weapons, and once the war got into the Trench Warfare stage it was nearly impossible for either side to win.Trench warfare started in 1914, and continued until the end of the war.
The history of the United States Marine Corps (USMC) begins with the founding of the Continental Marines on 10 November 1775 to conduct ship-to-ship fighting, provide shipboard security and discipline enforcement, and assist in landing forces.
The Marines were ordered into Da Nang to beef up defense of the air base nearby from which air strikes against North Vietnam targets had been launched. The 3,500 Marines dispatched on March 8, 1965, marked the start of the ground war in Vietnam. Members of the 9th U.S. Marine Expeditionary Force go ashore at Da Nang, South Vietnam, March 8, 1965, and run to assigned positions.
