The NS R3 Swarm is a Common Pool rocket launcher, similar to the NS Annihilator. Like the Annihilator an active (green) lock-on is required for being able to launch 1 of the 3 rockets that each magazine supports (so: no dumbfire possible), with a delay of around 1s between each shot, which each requires one more click. This means that the user will be exposed to the enemy for a longer duration than with any other lock-on rocket launcher. However, there are some advantages to this weapon. The fire mode may be changed while aiming, reloading and firing and will do so once the weapon is ready.
