Orcs Are Coming

Some of the fluff excerpts for the Ironjaw brutes are pretty good regarding how they organize. Proppa and humourous like an Orc:

"Things get more ‘precise’ when it comes to organising multiple mobs. These are gathered into fives, one for each finger a Megaboss can count on. These mob gatherings are known as fists, and just like the bunched fingers of an Orc, they are great for smashing stuff. In fact, this is often how a Megaboss will form a fist, showing a mob boss an open hand before closing the fingers and thumping them, much to the amusement of all involved. It is a brutally effective method of organisation and one that has worked for the Ironjawz for as long as any of them can remember. Not all Megabosses are created equal, however, and some have trouble getting even to five, especially if they have lost fingers or, worse, whole hands. Others are rare and talented generals, at least by Orc standards, and have discovered that if they hold both their hands next to each other, they can get to ten. Rumours tell of mysterious barefoot Orcs that can count even higher, but most Ironjawz don’t believe such fantastical tales."
