Black Trenchcoat, pretty solidly, and you see more of that in the Stand Alone Complex series. Most of their jobs are infiltration, datasteals, and sometimes wetwork, but they always try to be as discrete as possible. They are prepared to 'go loud' if that is the mission profile, but they are a group of tactical operators, not a bunch of rowdy gangers. Quick, clean, and methodical is their typical MO.
