You could also use the vehicle damage tableOriginally Posted by Harley
1-3 Crew Shaken -> Model is dazed, unconscious, senseless,... (Light injury, recovers normally)
4 Crew Stunned -> same as 'crew shaken' but more serious injuries (Light injury, recovers normally)
5 Weapon Destroyed -> serious injury to the arms (Heavy injury, must miss a battle)
6 Immobilised -> serious injury to the legs (Heavy injury, must miss a battle)
7+ Explodes! -> Dead
Almost the same but more fluffy (the story writes itself for your characters injuries ;-) ).
And you can make it as detailed as you want, with as many bonusses or penalties as you want, depending on which weapon killed your character, etc...etc...
(But perhaps it is best not to make it to complicated, you don't want your battle to bog down while you are taking notes what shot who :-) )
