The Galactic Institute for Tactics and Non-Conventional Warfare was a private consultant firm specializing in warfare and military doctrine. Beyond consulting and advice, the GI also gave hands-on assistance with its client's needs, utilizing mercenaries and its instructors. Institute consultants offered background information gathering, offering strategic purchases (advice on what to buy, helping obtain restricted hardware), training, and covert mercenary black operations. The firm was suddenly closed in 12 ABY when Oppenhiemer disappeared.
