Officers train at telegraph machines under the supervision of an instructor. Officers seated at desks in a classroom. Instructors take classes with the help of charts, diagrams and black boards. Officers seated atop electric poles for training. Two officers train in hand-to-hand combat at the OCS. Officers learn to use Radio Relay. Students listen to an instructor as he demonstrates the process. A U.S. soldier lays field wire across a hilly terrain to establish wire communications in the European Theater during World War II. Soldiers on the hill. Soldiers set up a sending station at the point where the wire can't go forward. A receiver is set up at the point from where the wire can go forward again. A soldier receives a photograph of a map through facsimile. Items of signal communication including radio relays, receivers, walkie-talkies, radio boxes and fuses to be produced and distributed by the USA Signal Corps to all other ground forces, navy and the Allies. New, modern, improved efficient signal communication equipment. A soldier displays two old type fuses and their counterparts.
The role and contribution of the U.S. Army Signal Corps in combat and war, especially during World War 2. Workers organize and prepare signal communication material and equipment for transportation. Men transfer the items including wooden cartons, cables, signaling units in trolleys. Workers load the material into trucks. Shuttle ships in docks. Signal communication supplies for U.S. and Allied troops in the European Theater loaded onto the ships. The shuttle ships make their way under security in heavy seas. A Nazi U-boat wolf pack in the water during the early stages of World War II. torpedoes launched and U.S. ships are attacked bu the German submarines, smoke due to the explosions. U.S. sailors on board and jumping from burning ships into water.German wolfpack submarine fleet in a harbor. German Kriegsmarine sailors lower German Neger torpedo-carrying craft (sometimes called Human Torpedo) into the water. A U.S. B-25 bomber aircraft in flight locates a German submarine. The radio operator gives the exact location and the submarine is attacked. View from within cockpit as bomb sight is fixed on German submarine target. View of bomb doors open and bombs away from B-25 aircraft. Explosion in water is seen and the submarine is hit. Dramatized scene from inside of submarine as it is rocked by explosion and fills with water.
The role and contribution of the U.S. Army Signal Corps in combat and war. U.S. shuttle ships loaded with signal communication supplies for U.S. and Allied troops in the European Theater make their way in the Atlantic ocean. The Squier Laboratory at Camp Alfred Vail in Fort Monmouth, New Jersey. A technician works on signal communication equipment in the laboratory. U.S. soldiers use mine detectors in the European Theater during World War II. The mine detectors detect metallic, non-metallic mines, wooden box mines, and mines in glass containers. Artillery soldiers bury large microphones into the ground in advance zones. The microphones relay back information on enemy artillery. Soldiers receive the information on radio sets. U.S. aircraft on a training flight simulating real combat situation: The aircraft lost in heavy rain and rough weather, looking for the location of Boston. The pilot switches on a modern advanced radar. The radar waves pierce thick clouds, are reflected by Earth's surface and display an image on the scope. The image shows the clear location of Boston harbor directly under the aircraft. U.S. bombers attack over the Channel coast on D-Day (6 June, 1944). U.S. soldiers employ meteorological equipment for long range weather forecast in the European Theater during World War II. Soldiers release a hydrogen balloon into the sky. Another soldier uses an apparatus to take readings of atmospheric conditions behind enemy lines. An aircraft drops an automatic weather station called SCM-18-TI by parachute into enemy territory. The timed mechanism sends out weather data in codes. The interior of the automatic weather station lying open in a field.
The role and contribution of the U.S. Army Signal Corps in combat during World War 2. Soldiers on guard duty in a field. A soldiers talks over a radio receiver at the door of a cabin. An antenna on the cabin roof. Signal Officers intercept enemy transmission by the mean of radio and other electric equipment. Electrical equipment, radios, deciphering equipment, laboratory equipment and parts seen at work in Signal Corps facilities where intercepted enemy communications are analyzed and codes and ciphers are deciphered. Officers skilled in encryption and decryption work to decode enemy codes and messages. They use a microscope to read and write messages in microscopic writing on grains of rice. Signal Intelligence work in North Africa during World War 2. U.S. soldiers on tanks advance over rough terrain. A formation of U.S. B-17 bomber aircraft in flight. Tanks advance with the ground forces. The radio intercept picked up messages from a certain German Division headquarters. A soldier sets radio direction finders on the particular location. Officers receive the information and locate the headquarters on a map. The Allied troops attack the enemy. They hit them with tracers. Artillery and guns are fired. Smoke from fire due to explosions. Soldiers advance in prone positions. They lie low during the night assaults. German soldiers load and fire a mortar. Explosions in a field due to mortar attack.
