G-2 was an original veteran soldier of the old Joseph Bonanno Family by the name of Giovanni "Johnny Bennett" Petrone, aka; "The Ambassador"

In general, Petrone lived a very shadowy existence, but he was reportedly a highly-ranked member of their borgata, who, at one point, was allegedly consulted with, and used as an intermediary, during the so-called "Banana War" of the mid-to-late 1960s.
