A command pack from
Warlord Games. The Germans have attached commanders in "To the Strongest" rules and I had seen something similar to this elsewhere (brains fading), and thought it was a good way to represent it.
My CinC is mounted on a round base to differentiate between himself and the sub-commanders.
The base was just a mdf beer coaster I picked up from a hardware store and sliced in half. Cheers.
