For 15 points and a comm slot this upgrade prevents enemies within range one from receiving orders.
15 points is a huge investment. That being said being able to control your opponents activations and timing is an incredibly powerful ability. If you are going to take this upgrade you need a reason and a plan to use it.
This upgrade is best on units that want to be in the thick of the action, who are also quite durable or hard to remove. Right now the best candidate is the AT-RT with a flamethrower, the AT-ST with grenade launcher, or any troop unit that can take it such as scouts or commandos. While this upgrade is powerful on a vehicle, because you can use cohesion to extend the effective range of comms jammer and more easily block LoS the best place for this upgrade is on a trooper unit.
