For "sometime later maybe":
A little inconsistency among mountain troops and light infantry:
mountain troops
German Gebirgsjäger: lightTreaded
Italian Alpini: lightTreaded
French Chasseurs Alpins: lightTreaded
Yugoslavian Mountaineers (Planinari?): guerrilla
Romanian Mountaineer (Vânatori de Munte): lightTreaded
Indian Gurkhas: guerrilla
French Goumiers: lightTreaded
ski troops/light infantry/jäger
SS Wiking: guerrilla
Finnish Ski Infantry (Jääkäri): guerrilla
Bersaglieri: guerrilla
Chasseurs Ardennais: lightTreaded
Mountain troops are trained to fight in most difficult terrain and climate, thus should rather gain guerrilla than light infantry.
Gurkha are basically mountain troops too, so it's fine here, while the other mountain troops usually won't see jungle terrain anyway.
Makes more sense if mountain troops (e.g. Alpini) loose no efficiency while moving around on mountains while light infantry (e.g. Bersaglieri) does a little.
Had the same issue within my mod that mountain troops lacked something.
I felt that heavy infantry and regular one were too versed in crossing terrain compared to specialized infantry.
That's why I gave heavy infantry and engineers
heavyTreaded and regular one
no trait instead of
lightTreaded. In particular heavy and regular rather consist of less trained men with lower endurance than elite troops.
lightTreaded for
light infantry already sounds very suitable, doesn't it?
Little tweaks that shouldn't also impact so much slightly modified vanilla gameplay.
