The Fortification Wall is a level 3 structure available to both the CORE and the ARM. It is not controllable and has almost the same purpose as the Dragon's Teeth; however it is much taller and thus can block even high trajectory projectiles. It blocks friendly fire as well though, so it is better used to cover high-value unarmed structures such as the Fusion Power Plant. While it is actually less durable than the Dragon's Teeth, it gets removed just as easily by construction units.
