Help with redemption at abridon pt 2

Well...this is a comen question i know but I can get the ship yard and the awing pilots but..I cant survive all the attacks for long. I servive about 5 but atretion wears my people down n they only come down so fast... help please

i haven't made it that far yet. i am at the volcanoe level after you place those homing beacons. :-) try building tons of defenses around your base (like troops and vehicles) then go after the enemy command center and blow it up (so they can't build any more stuff) and then wipe out everything else out (that's what i do).

Well I have the TRMB and as soon as I get it its like all hell brackes loose...
