When you start this chapter, you'll actually have no goal. You'll simply have to kill time in the city rescuing civilians. After a certain amount of time or after you've saved a few civilians (perhaps a combination of the two), your map will become fuzzy again. This time there will be three jammers. Head for a tall building nearby for a good vantage.
From there, look around for the red beams that indicate the jammers. Head for those and deal with each of them the way you did with the first one. When all three are removed, you may have to rescue a few more people but eventually, you'll have to return to your apartment. This actually ends the chapter.
