Radar Center
It is always important to keep track of your enemy, and especially when it comes to the time when the enemy is going to attack you. This is what you have the Radar Center for.
The Radar Center can be found in the Ward game menu, and will give you a nice big version of the graphical radar that you see in the control area of the Mech Wars game interface (unless you have disabled that, of course). The graphical radar will give you a visual representation of squadrons that are around your ward, and that are either moving to your ward, or moving from it.
A squadron is represented as a big dot, and the length from the middle of the radar represents how many hours they are away. You can see how long they are away by counting the rings that you see. There are three dots on the radar. The blue one, which is quite big and will always be found in the middle of your radar, is your ward. The other dots are for the actual squadrons, where red dots are for hostile squadrons, and green dots are for friendly squadrons. The larger the squadron is, the bigger it is.
Below the graphical radar, you'll find a list of all the incoming and outgoing squadrons, and how many units your radar systems believe there are in each squadron. Keep in mind, though, that this is only an approximation, and depends on how advanced your radar systems are. Please see Radar for more details about how this works.
Nevertheless, you will find a list of all the squadrons that are detected by your radars. This means that you can match the number of friendly versus hostile units, and see if you need to train more units, or perhaps try to get defence from your clanmates or allies.
