The MIRV Grenade (Cluster Bomb in ETF) is a secondary grenade in the Team Fortress series. When the timer goes off, it explodes like a regular Frag Grenade, but small bombs are released at the same time. These bomblets will hit the ground, then simultaneously explode after a few seconds. The Demoman are equipped with this grenade. This grenade can be used to perform a Grenade Jump, though it can only be safely performed when the MIRV first explodes. Trying to perform one when the bomblets explode will result in certain death for any class.
