OK. I wasn't trying to suggest anything like that. I was thinking of
something that had penalties going to infinity as ST went to negative
infinity. (Yes, I know, ST doesn't actually go to negatove infinity, I
hope you know what I mean.) If the armour ST requirement is up around
16 then someone with ST 12 is in big trouble, but someone with ST 8 is
in a lot more trouble so the curve shouldn't go flat on the left.

> The modern battle rattle when kitted can easily be over 50 pounds

British troops in Afghanistan are routinely carrying three times this.
See for instance
http://www.express.co.uk/news/uk/188986/British-soldiers-suffer-injuries-from-too-heavy-weights
. It is amazing what humans can be made to do. The sooner they get
this load off human backs and onto robots the better. (This may not be
an entirely fair comparison because soldiers would I think drop a lot
of this load the moment combat began.)

The heaviest load I ever heard of was (memory) 82 kg for the first
Royal Marines to land on the Falklands. (They knew they might get cut
off if the Argentine air force drove the ships away so I'm guessing
they had a lot of spare rations and organic capabilities which they
waddled up the beach with and dumped in a pile as soon as they
decently could. But I don't know.)

I think a full suit of mediaeval battle armour ran to about 40 lbs,
add in weapons etc. and it's probably comparable with the lethality
element of a modern kit, and probably carried by a smaller man.

Lots of things should be done via fatigue but aren't because fatigue's
a nuisance to track. To some extent the DX mods are standing in for
fatigue effects. In a game as simple as TFT that's perhaps acceptable.
