From left to right: Diamond/arrowhead shaped badge with red, white, and blue stripes with black material around it. This badge was used by the Twelfth Army Group as a shoulder sleeve insignia issued during World War II. The design, approved July 29, 1944, was used to show force in the red, white, and blue national colors of the United States. This unit was directly under the control of Supreme Headquarters, Allied Expeditionary Force, beginning September 1, 1944. It fought its way across Europe, encircling the German Army in the Ruhr Valley in April 1945. It was the largest force ever assembled by the US military. Germany surrendered May 7 and the Group was inactivated on July 31, 1945.
The red with white "A" in the middle with white design badge is unknown to what it means. My guess it was used to show when someone was in the US Army on their uniform.
Driver-W pin was approved in 1942 and was awarded to soldiers who completed training and met standards which qualified them to operate and repair military automotive machinery and wheeled vehicles.
From left to right: Gold staff sergeant grade 3 pin was used to show the ranking of the staff sergeants. A lot of times this pin was presented with the grade 3 technician patches as they were paid and ranked the same, but staff sergeants had more authority.
The middle pin is brass and was the pin given to people joining the Army during WWII.
The far right pin is brass with U.S. embossed lettering. This pin was given to anyone who served during WWII.
