The key link in the Lanios Defense Force's future plans, the Karaan transport facility, is in grave danger from an extremely large Alien  force and is in need of immediate protection.  
The defense force desperately needs this facility to survive - they plan to use it as a launch point for their offensive against the Aliens. You are all alone on this one and will have no backup.  
Many of our defensive units have been compromised by the recent security breach and are either captured or destroyed as a result.  
You will be dropped inside perimeter of the facility and from there you should begin your patrol.  
You must actively search out the alien transport pods and destroy them before any units damage the installation.  70% of the buildings must survive for the base to remain operational. 
The Aliens are swarming in from all directions - you will have to stay on your toes to manage this mission.  Good Luck, Scout.
