This is the first Strikeforce mission and you have to play it through at least once when going through the Campaign for the first time. When you do that, you will have to go through a short tutorial about Strikeforce missions. This will teach you the basics, such as controlling and switching units, how to utilize the tactical view and even how to assume direct control of a unit.
Once the tutorial is finished, the real mission will begin. You have one minute to get ready, before the enemy will start arriving. You are tasked with protecting three points from enemy attacks and if two of them are destroyed, a fourth unit will appear and this is your main objective. Should this one fall, you will fail the mission (which doesn't matter, as the campaign will still continue).
At the beginning, before the enemy arrives, go into tactical view and send the CLAW to the area between Point A and B. This should allow it to assist both areas. There should be one team of soldiers at Point C, with the other at Point A, preferably on the platform.
Enemy CLAWs will approach from north of Point A, with enemy soldiers coming from behind Point B, dropping onto the balcony to the left of Point A and to the far north of Point A. Quadrotors are another enemy you have to contend with in this mission, which will come in behind Point A.
Point A seems to be the one that is attacked most, and with CLAWs coming in from the north, you should be targeting that first. Point B is the next target, with Point C seemingly the least attacked. If you need to take direct control of any units, one of the soldiers or the CLAW is preferable. Once the 10 minutes have expired, get rid of the rest of the enemies to successfully finish the mission.
