Mission 3:
After u find the second HVU move downwards. When u arrive at the third square ur friendly forces will start to attack. Quickly, move to the far right side. make sure the HVU is at the end of ur collum, all figthers are up front, some are a bit left. Move forward one square by another. This is essential. Some enemys will spawn directly infront of u, a bit to the left. If u set ur fleets up in the proper way, ur fighter will attack the incoming enemys. Make sure u don't move, otherwise the fighters won't attack. U gonna loose some fighters, but the HVU should stay untouched. Continue to move downward at the far right side. Watch out for the enemy radar. A friendly force will spawn at the bottom left, and start attacking the enemy. Carefully make ur way to the southeast corner and continue moving to the evac point. Make sure u stay at the far bottom of the map while moving untill u r right behind the evac point.
