in this mission, frank wants us to get rid of the gang members that are plaguing the Strip. They are all marked on the map. The first is about 320m away, so head there. The gang members are holed up in a park-like area. you can take cover easily and get rid of them without too many problems. After that, head for the second group, which is about 300m away, near the fake Eiffel Tower. The gang members are in a tight alley, so if you drive in from the right direction, you should be able to run them all down, or at least leave just a couple left.
the third group is in the fort by the lagoon. Head there and take out the guys inside, who shouldn't cause you any difficulties. There are about half a dozen of them. Once that's done, this mission will be over. Of course, Benny will be taking the credit for all of your hard work.
