Tacticals (commonly referred to as Special Grenades in older games) are a class of grenades and tactical equipment that add a distraction or visual effect on the player's sight, while adding time for the player to kill or flee their enemy. They are used in most games of the series.
Portable Radar - Allows tracking of enemy movements, can be thrown large distances.
Call of Duty: Black Ops II
Smoke Grenade - Produces a smoke screen immediately upon impact, smoke cloud is slightly smaller than previous versions.
Concussion - Disorients enemies and slows movement via heavy screen blur and tint, rendering them almost completley unable to fight.
EMP Grenade - Disables nearby enemy electronic systems, can destroy them with several grenades.
Sensor Grenade - Detects enemy soldiers within line of sight, lasts several seconds.
Flashbang - Blinds enemies and impairs hearing, screen is filled with white light and hearing is filled with very high-pitched buzzing sound.
Shock Charge - Proximity triggered mine that electrocutes and stuns nearby enemies, does a small amount of damage.

Call of Duty: Ghosts
9-Bang- Able to be "cooked" for more detonations, up to nine flashbang- like explosions. At the maximum power, has a slight EMP effect. At the base effect of one charge, is identical to a single Flashbang explosion from previous versions.
Smoke Screen- Works identical to the Call of Duty: Black Ops 2 version.
Trophy System- Is almost identical to the Call of Duty: Black Ops 2 , but now rolls a short distance upon impact with a solid surface, delaying instant effectivness.
Shock Charge- Identical to the Call of Duty: Black Ops 2 version.
Black Hat- Similar to the Call of Duty: Black Ops 2 version, but much less effective. Instead of hacking things nearly instantly, it now works upon a meter to 100%, and aiming near the center of a Scorestreak makes it work faster. Aiming away from said Scorestreak drains the meter back to 0%.
Hell's Retriever - Pierces through multiple zombies at once when thrown, then returns to the player.
G-Strike - Attracts zombies, which become the target of napalm missiles.
Li'l Arnie - When thrown, will create a distraction to zombies, attracting all zombies to its area in which they will be instantly killed, up to any round, except Margwas and Panzer Soldats. Can be upgraded in Revelations.
