The Fortified Bunker, developed by General Shin Fai, was an improved version of the standard ChineseBunker. Its two main advantages over its predecessor were a 100% increase in troop capacity and a significant increase in armour protection. In addition, the Fortified Bunker came standard with surrounding land mines. All these improvements were made to the Fortified Bunker for a relatively low cost.
As with the regular Bunker, it was vulnerable to attack from long-range weaponry, especially the Neutron Shells from the Nuke Cannon
Completely filled with Tank Hunters, the Fortified Bunker was arguablly the most powerful anti-tank base defense in the game. When coupled with Gatling Cannons or Bunkers filled with Mini-Gunners, attacking infantry and airplanes (even General Granger's King Raptor) would be decimated and artillery missiles would be shot out of the sky, albeit only when employed en masse.
