Worn in both movies, a standard three hole military pistol belt is what the Ghostbusters use to carry much of their equipment into battle. They were gray in Ghostbusters and a grayish khaki in Ghostbusters 2. A leather strap with a keyring is used to hold the Proton Gun on the belt when it not attached to the Proton Pack. The belts are known to hold everything from the Belt Circuit, MT-500 Radio and Lifegard in Ghostbusters 2, to being a convenient place to hang their black rubber gloves.
