I think, in the next update of Tom Clancey's Rainbow Six Siege, there should be a new feature when you use your drone. If you see someone on defences gadget, it should ID them, like if you saw a signal jammer, it would ID the defender as Mute. this would make using the drones much easier, and making drones a little less useless when it comes to signal jammers. this could also work the other way, like if you see a shock drone, it would ID the enemy as Twitch, or even if you see one of Capitão's arrows land, it ID's him.
just a thought,
