Basic Information
A Fury TAC-nuke is more or less a nuclear grenade. It's easy to use and effective at destroying anything from an enemy base to a Covenant Cruiser, though you would have to get inside first and then begin the detonation. Over all, it's the size of a overinflated foot ball, but has a blast radius of about 1.2 km, and is extremely clean for being a nuclear device.
Known Uses
During the attack on Reach, Spartans Frederic-104, Kelly-087, and Joshua-029 (AKA Alpha Team) destroyed a Covenant Cruiser by capturing a trio of Banshees and throwing a Tactical Nuke into its grav-lift. The reason for this style of attack was due to the electro magnetic pulse (EMP) given off by the warhead. By throwing the Fury Tactical Nuke into the grav-lift the Tactical Nuke entered the Cruiser's hull. This used the Covenant Cruiser's shields to block the EMP and essentially preventing damage to the generators powering the Orbital MAC guns orbiting Reach. This kept the Covenant fleet from being able to get close enough to potentially glass the planet.
