From the TCCC:
60% Extremity Hemorrhage
33% Tension Pneumothorax
6% Airway Obstruction

Let's assume, for the purposes here, that we're talking about being stateside and with 30 minute response time from EMS and 60 minutes to get to an emergency room or trauma center.

Let's also have a goal of an AR double-mag pouch (or triple if needed) as a size limit.

I think anyone/everyone would include a tourniquet or two.

Trauma dressing (Israeli, Oales, Cinch-Tight, Thin-Cinch, 4" vs 6", etc.) seems to be a common theme.

NPA?

Better to use a dedicated chest seal or rely on the wrapper from the trauma bandage and some tape?

Hemostatics seem to illicit some controversy, but better to have and not need? Worthless stateside with 30 minute EMS response?
