There's a good chance you'll stumble across Cautionary Intel in Star Wars Zero Company and have no idea what it's actually for. Honestly, it's a bit confusing, especially when you notice the Den has a base upgrade with the exact same name and what looks like the exact same effect. But the game doesn't exactly spell out what happens once you've got it, so let's clear that up.
You can grab Cautionary Intel as a potential reward from the "Our Jedi Friend" critical operation, but only if you follow Neesh's lead instead of Bennic's. Hover over the reward and you'll see the text: it reduces the chance of Injuries on Dangerous Operations by 20%. That sounds straightforward enough, right? Except "Dangerous" is also the name of a mission difficulty in Zero Company. That's not what this is talking about.
By "Dangerous Operations," the game means any operation that has a chance of injuring the Operators you send out on it. Basically, it's a flat 20% injury reduction across the rest of your campaign. That's a serious permanent buff, so it's well worth hunting down.
Here's where things get extra confusing, though. There's also a Den upgrade in the Networking Chain called Cautionary Intel with the same 20% injury reduction effect. But earning the mission reward version doesn't unlock the base upgrade. They're separate effects from separate sources, which implies they stack with each other.
One thing's for sure: you don't want to sleep on this one. And if you're diving deeper into base building, there's plenty more to learn about, like where to find Capacitors or how many cycles you'll go through over the whole campaign.
