The regiment traces its history to the 7th Infantry Battalion, formed 1885, and became the 7th Infantry Regiment three years later. The regiment was formed during the Spanish–American War in 1898. Its initial training took place at the Presidio of San Francisco. It later served under General John J. Pershing during the Mexican Border Campaign of 1914. During World War I, the regiment participated in the French Meuse-Argonne Offensive in 1918 and the Battle of St. Mihiel. During the Meuse-Argonne Offensive, units of the 160th Regiment along with units of the 307th Infantry Regiment became known as the "Lost Battalion." Captain Nelson Holderman, a member of the 160th Regiment, was awarded the Medal of Honor during the Lost Battalion action.^[3]

The regiment's armory, located in Los Angeles, California, hosted the fencing competition at the 1932 Summer Olympics as well as the fencing part of the modern pentathlon.^[8] As part of the United States mobilization during World War II, the 160th was federalized at Los Angeles, California, on 3 March 1941 and moved to Camp San Luis Obispo, California, within two weeks. The regiment trained there for over a year as part of the 40th Division before relocating to Fort Lewis, Washington, on 29 April 1942. From there, the regiment went to San Francisco, on 1 September 1942, and was shipped to Hawaii the following month.

The regiment trained in jungle warfare there for over a year before being moved forward during January 1944 to the Solomon Islands. From April through December the regiment fought on New Britain Island during the New Britain campaign. The regiment redeployed through New Guinea and they invaded the Japanese-held Philippines on 9 January 1945. The regiment participated in various actions in the Philippines' Campaign (1944 to 1945) during the rest of the war.

Ryoichi Tozuka, the commander of the Imperial Japanese Army in Panay Island, signed the document of surrender at Cabatuan Airfield,^[9] located in Cabatuan, Iloilo, Panay Island, Philippines, on September 2, 1945, the same day as the surrender signing in Japan aboard the U.S.S.
