You can plan every aspect of the assault here. The diagram can be zoomed in and out as well as scrolled and rotated. The view can also be changed to a three dimensional representation. If multiple floors or levels are involved, the plan can be changed to view each one. There is a lot of information on this screen, use it to your advantage.
Some scenarios have more recon info than others.
This represents the availability of alternate sources of situational information, such as observation from other buildings, satellite recon etc. You may start having a good idea where the bad guys are, or where the hostages are located. You can see special landmarks, or various ways to gain entry other that storming the front door. The most important feature of this screen is the ability to assign waypoints for your fire teams. Each team can be given a starting position and waypoints to advance through the scenario.
