Deliver the encrypted intelligence to Lieutenant Seguine. He's located on the subcontinent of Concordia Divide, in a small Forean village near the western border. You can reach Divide via a cavern entrance beyond the rear gates of Twin Pillars base.
"Are you ready to expand your horizons, soldier? I need someone to head over the Concordia Divide."
"Here's the situation. One of our team found a crashed Bane dropship up to the north. The crew were all dead, but we discovered data disks in the ruins that contained detailed flight plans for attacks on Divide."
"I need you to deliver this to Lieutenant Seguine. He's an AFS soldier stationed in Nidu Dav to keep an eye on the western border of Divide. Most of the time it's quiet along the gorge, but I'm not sure it will stay that way unless he's made aware of this."
"Divide is an entirely different subcontinent of Concordia. The fastest way to reach it is probably through the caverns on the far side of Twin Pillars. Here, I'll mark the location on your map."
"So the Bane think they can sneak attacks in on us from the west? Oh, I expect they underestimate just what I can do - particularly with advance warning. Thanks for the intel, soldier!"
"Hey, you might want to go ahead and check in with Specialist Clifford. He's been looking for a runner to head out to the old Eloh ruins near here, and I know none of the Foreans like to go out there."
