My army falls primarily into this category, though sometimes I use it as a Reikland army (the colors throw people off, however).
My army is a loose brotherhood pieced together from soldiers all over the Empire with the goal of retaking Sylvania and purging it of undead. The colors of this army are the colors of old Sylvania: Red, purple and black. The leaders are various nobles, businessmen and religious figures who either can trace lineage back to Sylvanian nobility or they are interested for reasons of financial speculation. The rank and file are a mixture of those loyal to the leadership for various reasons and mercenaries. I have a number of Dogs of War units I can include when need be.
My army began as two armies, one a Border Princes themed Empire army and the other an Empire themed DoW army from the Border Princes, both with the same paint scheme to ease sharing of units. I came up with the background and changed the focus after I stopped adding to my DoW army.
Because it is an army from all over the Empire, I consider it a Reikland army in scenarios where my fluff doesn't fit.
I have based its organization on a modern U.S. Army battalion, modified (of course) because otherwise some of the subordinate units wouldn't make sense. For example, I have placed all of the artillery into a battery of its own (D Company) rather than break it into heavy weapons platoons and spread it out throughout the other companies. All of the cavalry falls under the Headquarters Company, though when I get more I may break it off into it's own company and shift the HQ Company to an HQ Detachment.
Here is a breakdown of my Army, by company, as it currently stands. All Models listed are models I currently own unless otherwise noted. The only exception is the BSB. Every company has a BSB listed, but as only one BSB can be fielded at a time I have one BSB model on foot and one mounted, not a seperate BSB for each company. Not all of the models have been fully painted as of yet (hey, I'm working on it). Units are not fielded as shown, this is just how I organize them (because I'm like that). Each company commander has a mounted and dismounted version.
