Situation is as follows: There is a woods hex 4MF from my broken unit (2 OG hexes and then the woods hex). I don't want to go there. I would rather go to a woods hex 5MF away (1 OG hex then uphill to the woods hex). However, the woods hex contains a friendly trench counter or has a path. May I use the trench/path to calculate my desired destination as 3MF?
B 27.6 LOWER-LEVEL LOCATIONS Infantry beneath a Trench or Sangar (
F8) counter may move/rout/advance/Withdraw-from-CC directly to any Accessible, non-Crest-status
lower-elevation Location without having to first exit to above that trench/sangar. Such move/rout/advance/CC-Withdrawal in the opposite direction, from a non-Crest-status position to beneath an Accessible higher-elevation trench/sangar
(as if moving from a connecting Trench), is also allowed if that Infantry unit and trench/sanger are in the same side's OB and/or the unit's side Controls the trench/sangar
Location.
There is no rule prohibiting routing units from taking the trench or path. In fact, just the opposite, the location you prefer must be used (everything else being equal, such as proximity of enemy units) because less MF can be used to get there, per A10.51. 3MF vs 4MF. The routing unit must take the shortest path in MF.
