15/18mm Prussian Landwehr - Just for Waterloo's Anniversary

A long time ago now, back when I started getting back into Napoleonics, the first unit I built was a Prussian Landwehr Battalion.

Seeing that everybody is going Waterloo crazy right now for some reason, I pulled out the old unit and took some new photos. The figures are a mix of Warmodelling and AB.

Edit: One thing I just noticed is that one of the figures has gone grey! Is he a ghost? What's happened here? Any ideas?
