The 5th New York Volunteer Infantry
My old casualty markers with wounded figures haven't worked out so well. Because they are flat and tend to get spun around, which changes the count. Or run over and left behind. :)
I tried some casualty rings. The ones I used were too big.
So I thought I'd try something that's period neutral, unobtrusive, and doesn't take up much room.
Oh and very cheap and fast to make.
