As the wargamers amongst us will know, we use various devices to mark formations, morale states & casualties.
Called "markers", they are often printed labels or dice but sometimes more imaginative & less distracting.
I've always aspired to more creative markers. I had a Napoleonic rule set that demanded cavalry, post charge, should be marked as "blown". If I had a suitable supply of buglers, I would have used them. "Blown"; get it?
With my new Colonial rules( 'The Men Who Would Be KINGS') I've definitely hit my straps.
Units, if shot at & shaken, become "pinned". To show this I've impaled a suitably landscaped disc with a small nail.
And units, whose commanders have been killed, need to be marked as "Leaderless". The Waterloo1815 Dervish set has a plethora of useless donkeys. These, painted & mounted on a washer, make a suitably wry marker.
