The units of the 70th Infantry Division Special Troops were activated 15 July 1943 at Camp Adair, Oregon. They trained there for their combat missions for the next 12 months. During that period, the division was tasked to provide replacements for U.S. Army losses in Europe and the Far East. This required new replacements and retraining of some of the Special Troops units. In late July 1944 the division entrained for transfer to Fort Leonard Wood, MO, and resumed training there. The last of the replacements arrived in early October 1944. After the three infantry regiments embarked for Europe during the first week of December, an advance party from the Special Troops units sailed for Europe on 13 December 1944, landing in Marseilles on 23 December,  and moved to the  Task Force Herren operational area in Northeastern France.

The main body of Special Troops sailed for Europe on 8 January 1945, disembarked at Marseilles 18 January 1945 and moved by road and rail to Northeastern France; they joined the division elements already in place and on  17 February 1945, began combat operations as a division.

570th Signal Company
Responsible for establishment and operation of the division message center and establishment and maintenance of communications from division Hq to the regiments, separate battalions, companies and platoons, to units while attached to the division and to adjacent units as directed by higher Hq.

Communications are almost as vital to fighting men as food. History recounts many a major battle where failed communications led to defeat. Trailblazers fighting in the Vosges were gravely handicapped by the brooding mountains that simply swallowed radio transmissions. When the radios failed, field telephones were used.

The 570th was responsible for maintaining the communications network. The field phones required lines to work and the 570th had to ensure that the lines were working at all times. That meant repairs at any time, anywhere...even under fire!
