Unit patches actually had no prescribed regulation position when sewn to the upper sleeve, but usually they were placed 1/2"-1" under the shoulder seam. The wearer's current unit was sewn to the left sleeve, while any previous unit might be placed on the right sleeve. Shoulder patches were seen on all troops in the Normandy invasion, but as the war progressed, it was more common to see no divisional patches (especially on field jackets).
