Troops / Holding Objectives 8th

I thought I saw on here someone making reference to "objective secured" in 8th edition. That Troops get a bonus for holding objectives? I recall this being a thing in previous editions but I don't seem to see this in the new edition. Am I missing anything? Any areas where Troops are necessary/get a bonus?

Yup, it's in the new codexes and has been leaked as part of the coming "Chapter Approved" rules supplement.
