The first medal is for Good Conduct.
The Army Good Conduct Medal is awarded for exemplary behavior, efficiency, and fidelity in active Federal Military service. It is awarded on a selective basis to each enlisted soldier who distinguishes himself from among his fellow soldiers by exemplary conduct, efficiency and fidelity throughout the specified period of continuous enlisted active Federal Military service. Qualifying service includes each 3 years completed after 27 August 1940 or, for first award only, upon completion of at least one year upon termination of service, if separated prior o three years. The immediate Commander must approve the award and the award must be announced in perminent orders.
During wartime the Army Good Conduct Medal may be awarded on completion of one year of continuous service rather than three. Executive Order 9323, March 31, 1943 lowered this time limit for service during the Second World War, and it was amended by Executive Order 10444 on April 10, 1953 applying the one-year ruling to the Korean Conflict, (1950-1954) and to any future period in which the United States is at war, including the war in Vietnam, (1964-1973).
The "A" is the 1st Army Patch which was worn from 7 March 1949 to Present.
Transportation Enlisted Collar Device
In 1919, "a winged car wheel, flanged, on a rail, surrounded by a rim one inch in diameter" was approved as the insignia of the Transportation Corps. The Army Reorganization Act, 4 June 1920, placed all transportation except military railways under the Quartermaster General. The Transportation Corps essentially in its present form was organized on 31 July 1942 as a result of the Army reorganization of 1942 and has functioned since then as one of the services. The present Transportation Corps insignia is based on that of the World War I Corps, with shield and ship's wheel added. The winged car wheel is for rail transportation and the Mariner's helm for transport by water. The U.S. highway marker shield is for land transportation.
The three oval patches are for European Theater Operations, and are upside down.
Worn: 30 September 1943 - 25 February 1944.
The design of the insignia, approved in 1943 by the quartermaster general, is that of twin thunder bolts which represents ground and air forces breaking the chain enslaving Europe. The thunderbolts form the letter "V," the "Victory" symbol, common to both the British and United States forces.
The three ribbon bars are also upside down.
