Launchers can be used for a variety of reasons and can be both offensive and supportive. In Ghosts launchers will be able to completely turn a game around.
If your team’s constantly being tracked by UAVs or have yet another Attack Helicopter.. grab an Anti-Aircraft Launcher and shoot them down. On the other hand, if the enemy team has control of a building and using it’s shelter to their advantage; go for the Grenade launcher or RPG and fire through the windows.
If your team is fighting against the odds, changing to a Launcher is often a very good idea.
