First objective is to destroy some enemy beacons so that he stays unaware of my presence. But beacons are heavily guarded and there is something like teleport. Second obective is to capture teleport with my marine frigates

Ah! You do not have to obey silly orders when you are the commander of the mothership. It is simply a trap for your wits. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
The beacon is guarded and the guards are teleported. The beacons can wait but anything you need to do shall be resisted.
Find the weakness of the guarding pieces and build their counter parts aletrnatively with interceptors and as I told you to be ready with at least 3 or 4 squads at a time. Then take out the guarding ships while you build the bombers that shall take out the teleporter gate and the beacon is all yours. If you try to take out the beacon first the gurds shall delay you until more ships arrive and if you try to take out the teleporter first by bombers his guards shall destroy your bombers. So strategy depends on understanding stage dependency.

What can the enemy do by the information gathered by the beacon if there was no teleporter to bring in the anti-crafts that he finds best to destroy your force?

How can the enemy protect the teleporters if you destroy his gurads?

That is why they call them strategy games. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />

If you have the resources and the time you should send in a sacrifice decoy that keeps the guards busy while you take out the beacon.
During which you build the force that takes out the guards followed by the bombers for the teleport.

Try it out and let me know. <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />
