From what I've read of the Talabeclander-list, is that they have far more ranged attacks than us. They are allowed to have more wizards, AND they are allowed to take an unlimited number of handgunners. Our army hasn't got the best armour save ever (most units don't have armour at all), so this can really force panic tests.
This gives us the following problem: with so many low-point cost units, we can't expect all of our units to be within twelve inch of our general. That means panic tests will be made against Ld7. However, if we start spreading captains all over the place to boost leadership, our magic defense is low. To solve this, warrior priests are an obvious choice. They provide leadership AND dispel dice. However their fighting skills are lower than that of captains, and since we don't have much magic offense, the Talabeclanders can afford to have more of them.
Either outfit your priests to fight captains, or avoid them, and use detachments to increase CR so the Captain will hopefully run off the table or get run down.
However, detachments are ALSO needed as shields for your main units. Therefore I suggest two or three units of state troops, each with an archer detachment and a fc/ sylvanian levy detachment, all of them led by a warrior priest. The unit of knights can ride on the flanks to counter the enemy knights, or at least weaken them. They can also be used to stop the wolf-kin. I strongly recommend NOT taking any light cavalry, since they are very point intensive and will not last long against the multiple units of handgunners. I don't think taking the marauders will be a good idea either, since they're far more expensive than state troops and can't take detachments. If you really want great weapons to beat up the Knights, then take greatswords. They're a bit more pricey, but at least can take detachments and a griffon banner.
As for artillery, I suggest taking a cannon over a mortar. Cannons are far more apt at taking out knights. Only take one, though- you're not facing any high toughness creatures.
I'll be getting back on the Middenland list later. Though I'm not fighting Middenlanders myself, we should be able to defend ourselves from them in case they try and attack us...
