The X3-JMR is an ISA jamming device in Killzone: Mercenary which can jam enemy comms and equipment for a certain period of time. It can be bought in Blackjack's armory for 1250 Vektan dollars.


The X3-JMR can be used to reveal cloaked enemies, shuts down drones, and prevent other enemies from using their VAN-Guards. It is also useful in some levels in Killzone Mercenary, as it deactivates land mines, allowing the user to pass through safely.


  • The X3-JMR is the only VAN-Guard that is regularly used by factions other than mercenaries, such as the ISA.
