I actually had these started around Christmas time, but I set them aside to do less detail demanding tasks.
Each sprue of Perry plastic Prussian musketeers has a Volunteer Jaeger running at the trail. As I assembled the three 16 figure battalions from the one box, I also assembled a 6 figure group of rifle armed skirmishers.
Volunteer Jaeger companies were attached to each Musketeer battalion. Coupled with the Fusilier battalion in each regiment of line infantry, and a Prussian brigade could put out quite a strong skirmish line. I'm sure the Prussians could have benefitted from a skirmish screen in their first game.
So I guess this a check mark on Phase 4?
