The title of the show is SG-1, referring to the first Stargate team. Throughout the show, other teams are mentioned and sometimes featured/murdered, but the main focus seems to be on just the first team.
What I'm wondering is if each of the teams is meant to serve a specific purpose. For instance, there don't seem to be other people like Daniel on the base, so maybe SG-1 is specifically supposed to interact with other cultures. On the other hand, SG-4 seems to just be a bunch of soldiers, so perhaps they're the muscle squad?
So, is there, for instance, an astronomy team (SG-7? ), or a botany team, or a mountain climbing team? Or is it just "pick some coordinates and roll a d10"?
