Editing Warhammer 40,000/9th Edition Tactics/Fortifications (section)

====Pros====
*Buildings are extremely tough; toughness 8+, 15+, and 3+ armor wounds are common.
*Fortifications can allow things that your faction other cannot take, such as buy-able terrain, invulnerable saves, or a tough transport to hold models in (such how all the Dark Eldar transports are made of paper...).
*Unaligned models can usually be fielded in any army without losing army bonuses.
*Building transports (using "transport" loosely) don't have the same keyword restrictions that your army has on their transports (so your primaris can hide in that Fortress of Redemption along side your Firstborn in the same transport).
