The Connaught Rangers got my vote out of national loyalty, but I'd be equally pleased to see a future release depicting the Grenadier Guards.
Quite surprised nobody's voted for that option (yet). I think that distinctive uniform of bearskin and scarlet tunic would look very attractive. It would be quite unusual to see it worn by figures in fighting poses as well, as it's something one would much more tend to associate with ceremonial duties in the UK.
Royal Mail released a limited stamp edition a few years back featuring vintage portrait photographs of a selection of VC winners from the Crimea. I remember one in particular which I used to have pinned above my desk showing a very tough looking Grenadier Guards NCO.
Anyway, whatever the result, lots of worthwhile options here, I'll be interested to see how the poll works out!
Cheers,
Molloy.
