Thanks all! yes, I loved Magweb, I would print rules from Nugget and MWAN on my work printer 20+ years ago. All those hard copies are long gone, though I am afraid.
Going to fiddle with some mechanics. Conceptually I think it is similar in function, if not mechanics, to shock in TFL rules. The more you get shot at / take casualties / experience stress the less effective a unit is.
Going to do some experiments, likely come to naught, but I will post the results here.
