The 0033X grenade, officially designated as the Nitrocellulose Incendiary Device 0033X, was a combat-grade explosive manufactured by Greff-Timms Industrial. This grenade, the 0033X, served as the regulation grenade for the Old Republic's specialized rocket jumpers. Sized comparably to a typical Human fist, it offered selectable detonation timings: either immediate or after a ten-second pause. Though remnants of these grenades persisted into the era of the Empire, their operational status was heavily contingent upon their preserved state.
