According to Censor.NET, the basis of the set of individual first aid kits is that of the US Army soldier:
1 Combat Application Tourniquet (CAT)
2 Celox or QuickClot
3 Israeli Wound Dressing (aka Israeli bandage)
4 Halo Chest Seal
5 Pneumothorax Needle
6 Nasopharyngeal Tube
In addition to the kits the soldiers are provided with training in tactical medicine, learning how to properly use the kit components, as well as what is currently at hand and can help save lives.
The action is part of the ongoing Patriot Defense project to supply the troops with kits and training.
