"The 50th Signal Battalion was activated July 1, 1940, at Fort Sheridan, Illinois, not long before the United States was drawn into World War II. In September of 1941, a portion of the Battalion was sent to Iceland, followed by the rest in January of 1942 in order to build a communications infrastructure for Iceland Base Command on the island. Upon completion of that assignment, the Battalion was sent to England to prepare for the invasion of continental Europe. On D-Day, June 6, 1944, the Battalion landed on Utah Beach in support of VII Corp and its assigned units, which continued until the end of the war in Europe." -- Amazon.com.
