Mmm. In the way a square is also a rectangle, yeah, though the other way around-PMCs would be private orgs. Think of Private Organizations as being any kinda NGO-Megacorps, non-profit organizations, ect on our side, and Guilds and the like on the other side. Some(though not all) of these might have a militarized branch, but not all of them by any stretch.

EDIT:Also hooray for being the person whose vote has a majority lead, if only because I'm so far the only voter!
