Fortified structure upgrade

The Fortified Structure is an upgrade exclusive to the Global Liberation Army, first made available to GLA generals rather late in GLA Conflict.
==Game effect==
This upgrade can be purchased at any palace the general in question owns, and only needs to purchased once, as with all upgrades inCommand and Conquer: Generals.
The upgrade boosts the armor of all the buildings that are affected (see below) that the general purchasing the upgrade owns. The affected buildings' appearances also change; after the upgrade, they will sport barbed wire and sandbag barriers.
==Affected buildings==
* Command center
* Supply stash
* Barracks
* Arms dealer
* Palace
* Black market
==Changelog==
* Zero Hour patch 1.03: fixed the problem that would cause GLA workers to stop gathering resources when buying the fortified building upgrade
