Fatigue guide

By Lit4ium, in Only War House Rules

Hey all sorry if in wrong section and new lol. I'm a pretty laid back GM. I've found a problem with how fatigue works. In the rules all I've found is using your fists, Critical damage, and extensive fighting cause fatigue. As a GM I play where if a leg hits you your getting some fatigue because of force of impact knocking wind out of you. My question is if any other Gm's do it my way or even have another way to do it? Thank you for your time guys on this matter.
