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.
In March of 1951 the force was expanded and named the 1st Amphibious Recon Platoon, and would continue to serve after the end of the war. In 1957 the 1st Company of Force Recon Marines was formed, and 2nd Company Force Recon was formed in June 1958.
