I'm digging this. There's a lot of interest. So let's see, so far we've got;

Platoon Sergeant
Possible officer / engineer (depending which you choose, RPC)
Radio
Gunner (da Pig!)
Doc
Rifleman 

That's not a bad crew, already. Gives us a solid amount of firepower, especially if Mr_Pink's rifleman feels like lugging a Blooper along, as well?

EDIT : Provided we're all accepted in our requested roles, of course.
