Editing Fortress World (section)

== How To Crack One ==

A fortress world is one hell of a defensive position. However, they are not invulnerable. To defeat it, assuming you've dealt with the surface to space weapons and enemy naval garrison as well as Orbital forts...
You'll to orbitally bombard it, presumably with OKKVs (Orbital Kinetic Kill Vehicles, aka Rods from God), nuclear bombs of normal and shaped charge variety, shaped charge preferred, and aim for the shield generation systems to soften the area up. Once the majority are gone, try to aim for long range emplacements, in order to minimize attrition. If you're of the chaos type, do try to get cults sabotaging and initiating uprisings. If you're Imperial, Vanus will do the same. Toss in some assassins to remove enemy leadership. Ok, you've successfully blown to bits the shields, and are now constantly raining hell onto the enemy. Time to start the invasion. Bring the Siege Tanks out, and push in one or two, maybe three if you have a huge force, points. At this point, it'd be wise to bombard the flak and other AA batteries. Once they are semi clear, deploy air units to put more holes in the enemy. Congrats, you just broke one of the walls. Now, while this is happening, begin bombardment of other cities and destruction of relief convoys from orbit. Don't let them send reinforcements if you can help it! The other cities should ideally be busy repairing the damage rather than sending artillery to your forces. Meanwhile, back at the coty you're cutting up, use OKKVs to tear down wall sections and cleanly remove resistance. Orbitally drop units in pods or use Elysians and Harakoni Warhawk units. Depends on your allegiance of course. Use them behind lines far enough that you will be able to reinforce them and relieve them. Repeat for each layer of defense, hopefully with some variation to keep them from adapting. Do this to each City. Congratulations, you just expended 10 planets worth of materiel to destroy one fortress world. This, of course, assumes you're not willing to Exterminatus this place. Exterminatus should be carried out via Asteroid or atmosphere burning. This should put a damper on their units. Go in and mop up. Done. As for taking one over, well, unless you have the memetic and psychic corruption agents of Chaos or the sheer idiotic love for the figthing itself of the Orks and a stupid amount manpower on top of that, good luck.
