What classifies something as an "Army"?

What about posting some pics! We hadn't army pics in ages!
I have a small Surprise army.
Pics later.

I have a small Cadence Army... It began when I picked up a double because I liked the different version, and then I sort of ran with it! I have about 10 now, plus some official merch, but nothing custom yet.. maybe when I get a pony room!
