Can't Survive against the Evil Dr.Thrax on Hard challenge, same as above Options

[RodentDung]

I set the game to hard and have struggled like a raccoon making a grab for someone's ice cream cone but can't survive the dead Dr. Thrax vehicle rush that he seems to have a fetish for. He sends in a horde of annoying crap just as he gets all those missile and rocket buggies that can light up my base from long distance. I've tried as both Ironside and the blond Alexander but always got wiped at the same point.

As Ironside, I tried going both tanks in a few tries and airforce in a few tries and both tanks & aircraft. All were equal disasters. I tried watching youtube videos of people going against Thrax but the sissies always set it to medium so Thrax doesn't attack them. The problem with Ironside is his tanks are too weak to destroy Thrax's vehicles. I've had tanks driving around in circles to avoid the toxin and fire constantly at the toxin trucks but can't destroy them but Iron's tanks are killed in one shot by both missiles and rockets. I tried the Mammoth tanks in one game they were destroyed instantly without killing a single enemy so that was an epic waste of money and GP. With the regular Iron tanks, I put on either a repair drone or one of the anti-tank boomerang drones on each and reserved my tanks behind the turrets to rush out against the missile trucks. Problem is, after my tanks start their attack run out from my hard-pressed turret line, they immediately are hosed down with toxins and the missiles destroy them instantly so my tanks fail to even destroy a single enemy vehicle. At least my bombers were trading one bomber for one vehicle, though that too is lame considering I'm not flying into AA defended territory cause the SAM sites are taken out earlier by the A10 command center strikes.

As Alexander I tried using the previously almighty Aurora Alpha which helped a fair bit but it's so badly nerfed in Shockwave that they get shot down so often and use up all my money and they are far too weak to attack enemy bases in nerfed form. Alex has decent armored vehicles and infantry but they would all be massacred before getting to the Thrax missile and rocket buggies. The Aurora only barely equals Iron's turrets for defense but are only a temporary relief before Thrax puts in his main attack which I've never once stopped cause he spews toxins and missiles all over the airport once my turrets are blown up the suicide bomber trucks. Also the oil derrick gets suicide bombed early too despite have turrets placed around it for protection.

As both Iron & Alex, I reserved 3 GP for the A10s to be able to hit the Scud and to take out the SAM sites on my side of the river cause they make a turkey shoot of the Auroras. I don't see any other way to damage the deadly Scud site. Auroras are guaranteed suicidal to send anywhere over the river so a strike on the Scud site would cost 4 Auroras at a price of $10,000 and leave my base undefended for about 5 minutes. I can't use infantry to defend cause the toxin kills them all instantly even with the ineffective chem suit upgrade.

Is there any way to beat the evil Thrax with Alex or Iron I wonder?? I want to stay on Hard level because I was able to beat the tank freak and the camouflaged terrorist on that level, only the deadly Thrax is unbeatable (so far).
