Instead of a patrol today, I was tasked by some officials from the Commonwealth with dealing with a group of Junkers that had been spotted too close to Guadalajara. So I took the Stryker and went to snuff them out. Upon nearing their position, the situation immediately turned hostile, with a greeting of blaster fire headed towards me. That didn't phase me, and I charged right into the fray taking out several of their ships with their own mines. They seemed to have nearly limitless backup, I don't know where all these ships came from, but there were a lot of them. No matter, I dispatched them all. In the end, I took 17 Junkers captive and brought them back to Guadalajara for trial.
I suspect the officials will send me on a mission to deal with whatever base of operations those Junkers have set up soon.
