On the low registration numbers, something that might help. I remember the Battle of Tunisia, the CO's on both sides fostered the individual squadrons to come up with period recruitment posters, sometimes representing the historical groups, fighter squadrons, tank regiments, etc. We had quite a number of creative recruitment posters for both sides showing up in the general forum all the time. There was a very immersive spirit for that scenario. It was also very educational for those who were WWII buffs.
