 * Arrest Field Commander Welling
 * Go to Dia Moroyo Post and arrest Field Commander Welling.

Briefing
Colonel Sherk:


 * Thanks to that Data Disc you recovered in the Dia Moroyo village ruins, there's enough evidence to have you arrest Field Commander Welling for conspiracy and treason.


 * I'm well aware about the existence of Penumbra. I don't like it, but I suppose all military organizations have a Black-Ops division.


 * If Penumbra was behind the concealment of a possible cure for the Foreans here, then I wouldn't have a leg to stand on to do anything about it. However, I did some calling around and it turns out that Welling is no longer connected with Penumbra. In fact, he's considered rogue. Seems that he's on his own agenda in this war. I don't know what it is, but I intend to find out.


 * I want you to head back to Dia Moroyo Post and arrest Field Commander Welling. Hopefully he'll come quietly, but he's a hard bird, so be prepared for anything. Come back to me when you're done.

Arrest Field Commander Welling
Field Commander Welling:


 * You have no idea what you're going against, soldier. You think the AFS and Penumbra are what's going to save humanity? Think again! One day you'll find out, but until then, say hello to some friends of mine...!

Debriefing
Colonel Sherk:


 * Dammit! This has to be deeper than just one rogue Penumbra agent. You say you fought a Penumbra Mech and soldiers? How the hell can that be if Penumbra said he's rogue...? Unless there's a splinter cell of Penumbra... I hope that's not the case. There's no telling where that'll go and how deep it actually runs.


 * In any event, good job. That couldn't have been an easy thing to do.

Head to Gangus Forward Base - also known as Moroyo Highlands Post - and confront Field Commander Welling. After some words, he and several Penumbra Operatives and a Penumbra Mech will attack. Other AFS personnel will help in the fight, so it shouldn't be too difficult. After taking them out, head back to Colonel Sherk.
