I don't think Jack called them rocks that often. I remember it happening every so often, but it wasn't a constant thing.
I think other teams had other specialties, though I suspect that they were probably cross trained to an extent. Ex.There was one team that was regularly mentioned to be ~ready to go in after~ SG-1 but I don't think they ever were actually sent on screen. At least, they weren't often, but "Going after other teams" wasn't their main job, iirc.
I also know that there was a named team [I want to say SG-2? But there's a very good chance I'm wrong on the name - it's been a few years] that was generally sent in after SG-1 to handle the details of actually setting up agreements and the diplomacy type stuff.
