Merc, Lanios scientists have detected an enemy signal at their newly constructed headquarters. They fear the arrival of a formidable Alien  force aimed at the destruction of the staging base.
This comes at a particularly bad time as the human forces are awaiting the delivery of key monitoring equipment via ground based transports.
They are asking that you be sent  to help defend the base and ensure the successful delivery of their equipment.
Your insertion point is in the main compound of the base.  You will have to leave the confines of the base to defend the incoming transports.  
As difficult as it sounds, simultaneously watch for an attack on the main buildings of the base and prevent our structures from receiving any damage.
You are to protect the main HQ and ensure that the supplies reach the compound safely.
