TABLE 6-4: CAMPAIGN TASKSEntrench
The army starts building field fortifications at a rate of 1GB worth/unit per turn. The army loses the benefits from the fortifications as soon as it moves.
Field fortificationsField fortifications represent a temporary or partial fortification, such as those at an entrenched armed camp or the walls of a village.
All armies are assumed to construct reasonably fortified positions at the end of each day's march – such minor fortifications are equivalent on both sides, provide no tactical benefit, and are not considered to be field fortifications.
In order to build a fortification significant enough to qualify for a field fortification bonus, an army must occupy the province for four war moves (1 action round).
Movement: No effect.
Combat: Units cannot charge into fortified areas.
Units defending a field fortification square get a +1 fortification bonus to Defense. Units in the fortification square get a +2 morale bonus to all Morale checks.
OoC:
Can troops entrench in the absence of (at least one unit of) engineers?
