The only problem here, the French uniform is clearly Napoleonic, which would make him a MUSKET unit (to be accurate)... of course the game replaces the French Musket unit with the "Musketeer".
You wouldn't be accurate using this unit as an "industrial age" Rifleman unit, since by the time the French were using rifles as standard-issue weapons, you'd be talking Franco-Prussian war uniforms, not Napoleonic.
I suppose you could replace the "Musketeer" unit with this one however...
