That clarification helps a lot - I think the idle actually clarifies it better Defend in a fortified area I guess allows you to control units that may survive an initial onslaught so the defense naming is apt - although defend castle could be better
Many thanks for the quick response - orders changed accordingly.
defense in a castle is usefull for those few units that recieve a bonus to castle defense...
Ptrolling is better in that patrolling armies might find scouts/spies/assassins/etc, and they kill unrestful citizens (raising the tax returns and increasing corpse #s.)
on the downside, if you prefer to lower taxes and maintain population numbers then patrrolling will not be the better option.
the best thing to do to defend that province is to invest in its local militia
Local militia can be awfully weak. As an example, Mictlan gets some slaves, and Pythium unarmoured militia. Jotunheim's and Ulm's pd can often be worthwhile, but I still prefer real troops in borders. However, when playing Ulm, I only have to bring infantry, and with Jotunheim, archers. The pd is the other half.
When you plan to have a strong army in a province for a while, not having a fort may be the better choice. In a no-fort province, everyone who isn't hidden will fight against an invasion. In a province with a fort, only patrolling units and PD defend against an initial invasion.
In the late game, you have to be careful that your patrolling forces are strong enough to deal with multiple castings of ghost riders (or strong forces teleporting / astral traveling in).
