The primary historic mission of US Army Special Forces is Unconventional Warfare. A 12-person Special Forces team infiltrates into an occupied nation at war to raise and train a guerrilla army to fight for the liberation of that nation. The OSS, a predecessor of SF did just that in Europe and multiple other occupied countries throughout the world during WW2.
Guerrilla or resistance forces fight with whatever weapons they are supplied with or recover from their enemies. An inserted SF team my arrive with their own US made weapons or deploy entirely with weapons typical in the occupied country. Even if they bring US weapons, eventually, if the resistance runs long enough, they will run out of ammunition for those weapons, or they may break.
A crucial skill set in Special Forces is the ability to successfully use weapons commonly available in your area of operations. You don’t always get to fight with the weapons you brought with you. It is foreseeable you will be taking weapons off your enemies to continue the mission (did you see our post on the French Resistance disarming & recovering weapons during WWII?) This is battlefield recovery. Figuring out how to use that equipment in the middle of a gunfight is a horrible idea: You need to be facile with their use ahead of time.
If you consider yourself a tactical medical professional, you need to train not only with the equipment you like and carry, but those you might encounter on your own “battlefield.”
How many of these tourniquets have you trained with?
Do you know the assets and liabilities of each?
Although many are of a similar “strap and windlass” design, their effectiveness in the published medical literature is very different. Are you familiar with the effectiveness? What is your backup plan?
