Combat Gauze is primarily used for bleeding that cannot be stopped with a TQ. Specifically where the pelvis and legs come together and where shoulder attaches to the torso. I carry 2 packages in my EDC pack (NF Recon that doubles as a school backpack and Daddy day pack). I have 2 TQ's, a 2" and 4" elastic trauma bandage, adult and pediatric NPA, 2 chest seals and tape. The youtube link is from the manufacturer on how to use Combat Gauze. https://www.youtube.com/watch?v=cgu8PtRDY2c
