Magazine Size	0 (9 flashes)
Starting Ammunition	4
Maximum Ammunition	4
Used by	Delta Force

The device is similar to the flashbang from previous Modern Warfare titles; however, after the first explosion, another eight 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".

"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. The longer it is held and "charged" the more effective it is. Fully cooking a 9-Bang creates an EMP effect which temporarily disables enemy SAT COM's and Sentry Guns. 

Trivia

Call of Duty: Modern Warfare 3

• There is a glitch that after first detonation, the remaing 8 flashes does not blind the player (PC Version).
• They do not appear in Multiplayer, instead the regular Flashbang grenade is used.
