The 9-Bang grenade is a throwable concussion device featured in Find Makarov: Operation Kingfish, Call of Duty: Modern Warfare 3, Call of Duty: Ghosts, Call of Duty: Black Ops 4 and Call of Duty: Mobile.
Find Makarov: Operation Kingfish
John "Soap" MacTavish uses a 9-Bang during the assault on one of Kingfish's safehouses.
Call of Duty: Modern Warfare 3
The device is similar to the Flashbang from previous Modern Warfare titles; however, after the first explosion, eight more detonations occur in fast succession, hence the name "9-Bang". It is only used by Delta Force during the campaign. 9-Bangs are first usable in the mission "Black Tuesday", where Sandman orders the player to use them on multiple occasions. They are also usable in the missions "Hunter Killer", "Bag and Drag", "Iron Lady", and "Scorched Earth".
Call of Duty: Ghosts
- "Holding produces more flashes to blind the enemy. Fully cooked 9-bangs create an EMP effect that stuns electronics."
- — In-game description
The 9-Bang grenade appears in Call of Duty: Ghosts, this time available in multiplayer, whereas in campaign only the standard Flashbang is available. After every 0.75 second increment, one flashbang effect is added, and after 2.5 seconds, it is fully cooked and will finish off with an EMP effect after the flashbangs. If it is thrown without being cooked at all, only one flash occurs.
The EMP effect from fully cooking a 9-Bang temporarily disables enemy ground based equipment. Strong-Arm is a very useful perk due to it decreasing the time it takes to cook the 9-Bang to only 1.25 seconds. The flashbang effect has an 800 unit radius, or 20.32 meters, and a 512 unit range for the EMP (13.0048 meters).
