Prior to the introduction of the numbered "scrolls", the 2nd and 5th Rangers wore the "lozenge" style of SSI. Wear: 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 with which he saw combat might be placed on the right sleeve.
