I'm in hikermor's boat - always willing to learn new lessons from deployment medicine learned the hard way, but for WFA scenarios we see pretty much the same lesson, direct pressure treats most major bleeding wounds (every one in my less than universal experience). That's not to say a tourniquet can't be applied in other scenarios, but I will be curious to see how or if the tourniquet advice could be applied in scenarios where you are 24 hours from better medical care. Meantime I would have a high level of confidence in stopping bleeding using non-TQ methods.

That said, I still stuck a tourniquet in the trauma bag kept in the car, but in 99% of auto accidents I would not be inclined to apply it.
