The tape must be affixed to all helmets. However, in combat areas the tape may be removed, as the crew commander directs. White and red reflective tapes are recommended, as they afford the greatest detectability y. When applying the tape, you use any pattern specified by the unit commander, as long as the tape pattern covers a minimum of 100 percent of the helmet visor housing and outer shell. To apply the tape, you should preheat both the helmet and the tape to approximately 100 “F. This improves the adherence qualities and ease of application. Aviator helmets should be taped in accordance with the provisions of chapter 7 of OPNAVINST 3710.7 (series) (general NATOPS) and any type commander directives. 4-22
