In combat, everyone is carrying a TQ, usually multiple. You have to reduce the threat before you can evacuate wounded, so if you are the wounded and are conscious, you need to be able to do as much as you can.

I have tried (on real patients) an improvised TQ, and they are not very good. It usually takes multiple tries to get it tight enough, if you can at all without ripping the material.

As for Quick-Clot, get training, use the gauze, know what you are dealing with. It works if used properly.

In military operations they do not use IVs for replacing blood loss. It just produces red "koolaide". It provides very little benefit to the casualty beyond a certain point. They use whole blood when they have it. IVs are gold for other issues, such as dehydration (which may be the most common casualty in the timing/camping world) and people suffering from biological infections, to keep them hydrated and give them some minerals and energy.

Unless there is spurting blood, I will try a pressure bandage first, except in cases where the bullets are flying and help may be a while. The SWAT-T and elastic wraps can help a lot with this. The pressure needed is great. You can't just press with your fingers if it is really serious. You are pressing with your hands, arms straight, and with your body weight behind it. It will cause pain to the casualty (as will a TQ), another person there to control the casualty is very helpful.

Blunt trauma is different from penetrating trauma. TQs may not be as necessary for blunt trauma, where pressure usually works.
