Nice to see some interesting gun selection in the second season, though. If the SCC crew are so inclined -- and if logistics will permit; I don't know how the prop departments handle this stuff -- they could have a lot of fun with different kinds of weaponry.
Another way to handle a Terminator: as we've seen in previous episodes, you can cause serious annoyances for a Terminator if you damage its tissue to such a degree that it can't readily pass as human. That might be a legitimate strategy to employ, particularly against the socially-skilled models. (Shirley Manson would, of course, be another story.)
