This is the first part of the Euric operation.  The goal of this operation is to eliminate the alien supply lines, thus crippling their war effort.
The convoy you are assaulting is very large and appears to be separated into three parts.  You will be dropped south of the convoy's entry point.  
The Protectors have managed to secure Two Voltar Sar-2 Shuttles to assist you in this mission.
You must destroy all alien convoy units before any of them reach their destination.  The first convoy will be very close at the time of your arrival, thus you will have to move quickly.
The convoys are spaced at approximately three minute intervals.  All units must be destroyed as quickly as possible for this mission to succeed.
