Launchers are weapons which fire explosive projectiles that are featured throughout the entire Call of Duty series. In Call of Duty 4: Modern Warfare and Call of Duty: World at War, they are available only as perks, however, in Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, Call of Duty: Modern Warfare 3, and Call of Duty: Black Ops II they are available as secondary weapons.
Launchers have many different purposes. They can be used as indirect fire support, anti-armor, anti-personnel purposes and anti-air purposes.
The different types are as follows:
Unguided Launchers: Fires unguided rockets to destroy targets, mainly enemy soldiers, and includes weapons such as the AT4 and RPG.
Guided Launchers: Fires lock-on missiles to fly at targets; they can be in direct or top-attack profile flight. Must have a lock on-to track like the Javelin and the Strela-3.
Panzerschreck - used by the Nazis. Can be obtained in Campaign and Multiplayer. In the mission "The Mace" you need to equip a Panzerschreck to destroy a tank. In multiplayer it is used by the Wehrmacht (Axis)
Bazooka - Used by the Allies. It is used by the Americans (Allies) in Multiplayer.
In Call of Duty 4 : Modern Warfare, there are four actual launchers in-game:
AT4 - The AT4 is seen in Call of Duty 4: Modern Warfares campaign being used by the marines.
Javelin - The Javelin is seen throughout Call of Duty 4: Modern Warfares campaign being used by the player many times to take down enemy tanks and aircraft.
RPG-7 - The RPG-7 is seen throughout the entire game, first seen being used by enemy troops throughout the campaign. It is used as a Tier 1 Perk in multiplayer.
Stinger - The Stinger is used at the end of the campaign mission "Hunted", where Gaz tells you to shoot down the enemy helicopter. Can also be used in "All Ghillied Up", but not recommended.
In campaign mode, the player can obtain a Panzerschrek in many Soviet missions. It behaves in a similar way to the bazooka, the only difference is that it has a blast window of sorts which limits peripheral vision, as well as being much less accurate. The Bazooka can be obtained in the levels Hard Landing and Downfall.
The only launcher available in Multiplayer is the Bazooka, taking the form of a Tier 1 Perk, much like the RPG-7 in Call of Duty 4. The Rifle Grenade is once again available as an attachment, also using the 1st Perk slot.
Launchers are now classified as secondary weapons. Altogether, there are only six launchers:
AT4 - A multi-task, all around launcher that can both fire unguided or lock-on.
Thumper - A grenade launcher. It fires 40mm grenades.
Stinger - A lock-on only launcher. Can lock-on to air targets.
Javelin - A launcher that launches missiles up to a high altitude before descending on targets below. Can be used with lock-on or fired on a specific area with precise aiming.
RPG-7 - An unguided, rather unpredictable yet very powerful launcher.
