 ===== Army Size =====
-Each defence point contributes a single CR8 unit as active troops.  It might be a dozen foot soldiers, half-a-dozen veterans or a few cavalry troops.  The 'standard' unit might have a dozen scouts or halberdiers,  a veteran unit might have eight 'Sword and Board' vets with medium armour, and cavalry units will be a bit smaller still.  That makes Army Size calculations a lot easier, has some Historical validity and accounts for extra costs associated with better troops.  You can find basic descriotions of the troop types I use in [[pathfinder:off-the-shelf:military:start |  this section]], but you can design your own troop types if you  want to.  Just try to keep them at about the same levels :)

-If each unit is a CR8 encounter, calculating the size of the army is fairly straightforward using the Encounter Scaling guidelines on [[https://www.d20pfsrd.com/Gamemastering/#Table-Encounter-Design|The pathfinder SRD]].
+If each unit is a CR8 encounter, calculating the overall CR of the army is fairly straightforward using the Encounter Scaling guidelines on [[https://www.d20pfsrd.com/Gamemastering/#Table-Encounter-Design|The pathfinder SRD]].  The easy way is to multiply the total number of defence points by 535 and then compare to the Total XP column in that table.  If you are within 10%, round it up to account for hangers on, casual supporters and the like. That is the strength of your army.
+There can only be one army per side.  If two or three armies come together to take on  a common enemy,  recalculate the CR value for the new larger army.
+===== Sieges =====
+Sieges have always been more difficult that open battles, and even taking buildings with light fortification or defence is more difficult than taking, or burning, civilian properties. This is because there are more combat trained people about, that can fill in when required. Under the Campaign rules there are a few troops that were left at home, auxiliaries and militia – and then there are all those guys who are too old to go off on active duty. However, they can fire crossbows from the walls, chuck rocks over the battlements, pour hot stuff through murder holes or poke spears at anyone who comes close. So …
+  * If the troops are at home (ie not out as part of an army) Defence Point Value for every fortified building, villages with palisades, or towns/cities with walls is doubled.
+  * If the troops are away, with the army, the buildings are defended by those people left behind – so defence points still count (but at normal value) if the building or settlement is besieged.
+The problem arises when you have a city with some districts inside the walls, which benefit from defence, but more districts outside the walls that don't benefit from defence.   There is nothing to stop a marauding army destroying those districts, when the army is away from home.
