The main feature of these defenses is the ability to cause massive amounts of damage with few defenders, the first line of defense is the five camouflaged bunkers placed at strategic locations in front of the walls, these bunkers have mounted cannon, preferably AX-43s these cannons rip through enemy troops and can destroy siege vehicles if a concentrated attack is possible. These bunkers are best used by dwarfs who can utilize the small tunnels connecting the bunkers to the second line of defense, the trenches. The trenches have 4 gun emplacements and two gun pits, the total number of people in a full crew for the trenches is about 30, 5 in each gun pit, 3 in each gun emplacement and 8 to carry shells where ever they are needed. The gun pits are manned by 5 soldiers carrying DC-12 infantry guns, each gun pit also has 10,000 shells for the DC-12s. The gun emplacements have HX-59 heavy cannon, ideal for taking out flying creatures and siege vehicles. These cannon require 3 pople to operate, one aiming while the other two load the 50-pound shells into the cannon, shells are kept about 20 feet down the trenches to minimize damage from explosions. If the trenches fall to the enemy, which is extremely unlikely then the final line of defense sets in: the walls. The walls tower nearly 100 feet straight up, they are made of granite and are about 8 feet thick. There are many arrow slits lining the walls along with an alcove for a XN-201 Heavy Artillery the XN focuses on destroying groups of enemies or siege towers. At the top of the wall there are mounted AX-51s, mostly focused of destroying flyer's but if the enemy gets too close they can take a few down before they get to the gates. Only one army has ever conquered these walls, and they only did it by attacking from a mile away with XM-205 siege cannons.
The East Fortifications of Grenarth hold
We charged their walls but the defenses held us off, hidden bunkers sprang out of nowhere and turrets wreaked havoc on our forces. Gun pits blasted our army to pieces and we pulled back a shell came out of the sky and destroyed several siege towers, we where finished.
