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.
On 1 February 1944 a new 1st Battalion, 4th Marines was activated by the redesignation of the 1st Marine Raider Battalion to 1st Battalion, 4th Marines. For the remainder of World War II the battalion would fight at two of the bloodiest campaigns in the Pacific, Guam and Okinawa.
