These are fusiliers and are correct, as far as I know, with the exception of the sabre-briquet which was only carried by the voltigeurs and grenadiers. I missed this on my first over-awed viewing of them, but it was pointed out by a friend. It would be nice if this could be corrected, but it's not a 'game breaker', at least for this little black duck!
It does make one wonder, what other surprises Strelets have planned?
Polish elite companies marching?
Scottish centre companies marching?
British flank companies marching?
The above types for the French, Italians, Swiss, Westphalians...!!!
