The RPG (Rocket) can be used as a Perk 1 perk, which will allow the player to spawn with 2 rockets. However, this perk cannot be accessed if a player's primary weapon has a grenade launcher or grip attachment. if hip fired the RPG has horrendous accuracy: the rocket spirals and often misses its target unless it's at close range. but using the sights improves this to an extent, often capable of darting into a window at 50 yards or more
The RPG is typically used to shoot down enemy helicopters, as it is the only weapon that can do any significant damage to it. One shot from an RPG alone will not be enough to bring down a helicopter however, and a second RPG or a few more shots from a primary weapon are required to bring one down.
One direct hit with a RPG does 1000 damage to a helicopter which sports 1100 Health. Sonic Boom further increases that damage by 25% to 1250, making it a 1-shot-kill.
