This is the black/silver version of the F-15E Day/Night patch that has *335 HOURS* (in SILVER text in the upper right quadrant) for the 335th Fighter Squadron aircrew members flying out of Seymour Johnson AFB, NC. As one of the F-15E Strike Eagle operational squadrons, this patch is worn on the left sleeve of the flight suit when you achieve that number of hours and DOES come with velcro already attached.
