"The River Rat Patch is a classic style military patch tab made for Veterans. Comes in an OD Green with black embroidery lettering that says “RIVER RAT”. On the back of this military insignia, it has a glue/heat seal back to have securely placed on any apparel. This patch tab is the perfect size measuring 3 5/8" x 1 5/8". A river rat was a group of men in Vietnam who wore black berets in the brown-water navy. They were tasked with firing machine guns on fast-moving boats and also on low-flying helicopters. This would be a perfect gift for Veterans during the holiday season, military holidays like Veterans day, or any special time of the year. Veterans this would look great on your sleeve or anywhere you feel fitted.
