I'm with Justin on this one, I thought we wanted to set this much closer to ANH because of the 30th Anniversary. Meaning the troopers would be in plain old Stormtrooper armor with no markings or anything. The SAGA2 Sandtrooper would be a perfect choice for our basic troopers. We could mix in a few Scouts and NCOs here or there too.
I think 15-20 troopers won't be enough. I understand we need are going to have a small number because it isn't a strategically important planet and the local police take care of most of the work. But depending on the size of the diorama we are going to need a platoon of troopers or so. A platoon is 3 to 4 squads, for those of you who don't know. And a squad is made up of 8 to 12 troopers. So we are talking somewhere from 24 to 48 troopers. I think it'd be best to have a mid sized platoon with either 3 squads of 12 troopers (36) or better yet 4 of 8 (32.) I suppose it wouldn't even have to be even squad number, we could do 3 squads with 10 troopers and a fourth squad with 8 scouts that can be broken down into 2-4 teams. Or something like that.
As for officers and NCOs, we only need one officer, a lieutenant, as platoons are led by a single lieutenant. And each squad is led by sergeant. I think we could maybe base their uniforms off hemble's Imperial field officer from awhile back.
We can also have a few pilots and naval troopers if we really want to have a small naval presence. But based on what we are talking about, it doesn't seem like that will be the case. I'm kind of a military buff, so this kind of stuff really interests me. I think it be pretty cool to have a militarily accurate Imperial force. I've got several more ideas on how we could set all things military up, but I'll hold off for now and see what you guys think so far.
