Been out a few years so I need an update. In my day, most of the Army was mended/held together with the ubiquitous black tape. I never heard it called anything else but "black tape". In civilian life, most people call strong adhesive tape of this type "duct tape". What is the current in-service term - "black tape", "duct tape", "Duck tape" or something completely different. I only ask because I want to know.
