Well -- since weapons are involved, some medical stuff. As a minimum, a military-style tourniquet and two 6" Israeli bandages.

Something to keep you dry, gather rain water, etc. - a light weight poncho or space blanket. Orange if you want it to double as a VS17 panel to signal for help.

A medium or large, high-quality folding knife, serrated -- such as a Spyderco Endura (or equivalent).

A hundred yards of 550 para cord -- that's your spare shoe laces, a snare to catch little wabbits, something to hold up your waterproof sheet, a tourniquet, rope to bundle firewood, etc.

Etc.
