Light Infantry... what the ****

[Pocus]

in the same trend, perhaps heavy terrains can give added fatigues to troops, each round. This added fatigue is moreover not given linearly, but is derivated from the encumberance, so that light troops get only +1 penalty in the heaviest terrains, while HI get an added +2 to +4:

unit encumberance; added fatigue:
1-3 : +1 in swamp or mountain
4-5 : +1 in forest, +2 swamp or mountain
6-7: +2 in forest, +3 swamp or mountain ...

modify this by -1 if terrain survival ability is presents.
