Check the manual for rates of movement in various types of terrain - the unit type makes a difference. In Jungle and especially Jungle/Rough movement will be very slow and your troops will suffer fatigue up to about 30, disruption up to about 12. Some of this is malaria effects. You can only reduce this by putting your troops in rest or reserve mode (but do not cancel the destination set - they will continue to move in those modes, but more slowly).
IIRC the barely visible Kokoda track between Buna and Port Moresby acts like a dirt road - units can cover up to 15 miles a day on it. This is not historic and does not fit the terrain type, but players were reporting this kind of movement rate.
In Uncommon Valor Kokoda is a trail, but WITP doesn't have trails.
UV had regular roads and trails, but not highways.
WITP has highways and regular roads, but no trails.
There was also a far heavier supply attrition across terrain without roads in UV.
It was almost impossible to supply a land move from PM to Wau in UV.
??? Why are you bringing up UV Hans? Did you mean AE?
I realize there are no "trails" in the game, but players were reporting that their LCUs were making the trip between PM and Buna (both ways) far faster than should have been possible in Jungle/Rough terrain. Something is happening where the historic Kokoda Track was.
I remember some players wanting to have the worm-hole fixed, while others said leave it alone. I don't know if subsequent updates and patches changed it.
