Shepherding 101
Background
Continuing where the last mission went off, another tracking attempt is made.
Walkthrough
You'll continue off from Resupply and Revelation, so destroy more Shivans while you're at it. You will have Beta Wing (consisting of four Hercules Mark Twos) added to your wingmen list.
Just kill more Shivans, then let the bombers escape. Continue on to the next part, which is Striking the Line.
