Example battle:
On a cold morning of spring, a Northerner cavalry force serving the Conricht family crossed Eastwatch's bridges and arrived at the gates of Altaregia, south of Shipbreaker Isle. While they hoped to pillage the city, they were surprised to see a Southerner army leave the gates and go into position in the field, to meet them in a pitched battle and spare the city of any further atrocities. Both generals were confident that they would win; however, only one could come out of this day victorious.
Northerner forces:
4 Berserker Cavalry regiments: 16 strength, 4 tactics, attempt to split one unit (strength 4 or below, strongest fitting in that category) every round
Southerner forces
3 Cavalry regiments, 1 Heavy I regiment and 1 Archer 1 regiment: 12 strength, 3 tactics, attempt to flank every round
Therefore, Northerners roll their tactics with +1 and southerners, -1.

------------
In a short an brutal battle, the southern general watched astonishingly as the northern cavalry, inferior in numbers but superior in mobility, picked apart the southern troops and massacred them one by one, ignoring the enemy attempting to get against their flank (and often failing, as the southern cavalry started to get torn into bloody bits by the bloodthirsty northerners). Citizens of Altaregia watched with despair as their defending forces got massacred. The victorious horsemen moved in to occupy the city instead of looting it, as had been their intentions. The northern general was named a war hero; two weeks later, a southern army counter attacked by wiping out his army and putting his head on a spike, then set Shipbreaker Isle on fire and ruined most of Eastwatch. The War of the Hounds kept on going, and this one battle was quickly forgotten by most men.

Alright, students. What did we learn here today?
Also, Cript, it's alright - you can even change the second trait to simply "+2 strength when defending". Diplomacy will be used as charisma.
