"Typical. Forget the reconstruction of Taris—I've got to shift everything around and help with some "top secret mission" nonsense!"
―Colonel Gaff[src]

Gaff was a Human male colonel in the Republic Army who served as the local regimental commander of Republic forces on the planet Taris. He was ordered by General Garza to assist a Havoc Squad lieutenant with a mission, but was not told what the mission was. Because of that, Gaff was reluctant to help, though his subordinate Elara Dorne cited a Republic regulation that allowed her to assist Havoc Squad without his intervention.
