Heh... Sorry, forgot to get in here too. I'm currently busy with Final Exams, so I won't have the time to finish my army. But here's the first support ladder, which is information gathering/reserve soldiers.
First support ladder, total 178 points
Succubus (CR 8, 64 points)
* 20 Fiendish human fighter 1 (2nd level equipment) (CR 2, 80 points total)
* 18 Eagles (CR 2/3, 8 points total)
* 26 Fiendish dire rats (CR 1, 26 points total)
The succubus is used for the information gathering, the eagles are there to deliver messages (though if the need arises, the succubus can just teleport). The fighters and rats are my reserve. I'll be adding one more higher-level monster (most likely some kind of demon or devil) to lead my armies, the rest will be mooks.
