I would like to start this topic out with a story of a SAPPER Course Instuctor I had....

This Sergeant was struck by a piece of rebar in the thigh just above the knee, and then it exited the leg. This was during combat operations in Bosnia. Operations were ongoing and no MEDEVAC was available (or medics). He had no trauma dressings because they were used earlier on another casualy, so....

He wrapped his leg with Duct Tape. It held for three days and he did not receive any serious infections.

I know most of us have used Duct tape for everyday jobs, even to fix a couple ripped hoses in cars, but I would love to hear what ingenious things can be done with this stuff. I mean things that have been tried in first aid or survival scenarios. Thanks as always.
