Downtown is a building-to-building crucible with plenty of vertical exposure to test a squads reaction to contact. Controlling elevated positions is key, as well as communicating movement and keeping track of the spaces your squadmates control. It’s also a good idea to leave a squadmate or two back to respond where needed once you start taking contact.
Assault must maneuver carefully to the Guidon flag, and move it to the extract point on the far side of the map. This is difficult to accomplish until OPFOR has either been distracted or thinned out enough to slip through.
