The Ogre are giant humanoid race that used by the Empire as shock trooper due to their large size and powerful physical strength than can swing a large hammer to kill dozen of soldiers in one swing.
During the Imperial Civil War, Zorzal uses these creature as tank buster and shock trooper against JSDF and Legitimate government force. It is shown that they can wreak and topple a Humvee easily or put some considerable damage to a tank with the brute strength and huge melee weapon like giant hammer or club. They also quite durable especially when they are outfitted with full body armor since they can endure dozens shot from 50 cals until they drops death in which gives them some time to wreak some damages to the enemy.
However, their tremendous physical strength is also their weakness since they are very slow in battlefield in which giving JSDF or the Loyalist plenty of time to shower its with rains of bullets or arrows until the ogre can get close to fighting position. Despite their endurance and heavy armor gives them resistance against bullets as strong as 50 cals, they are very vulnerable to explosive like grenade, anti-tank weaponry, explosive magic or cannon no matter how thick its skin and armor are since it only takes 3 to 4 grenades to kill one armored ogre, one blast from a tank cannon can blow a head or make a hole in the ogre as well as the fact powerful magic user like Lelei can kill an ogre easily by blasting its with her explosive magic rapidly. As the result, Zorzal's force often use them in ambush tank and soldier like the rest of the Imperial soldier rather than open field but due to their slow nature it takes dozens of them to bust a single tank or ambush a platoon of JSDF since they are slow enough to give a tank or JSDF soldiers plenty of time to blast 3 to 4 of them until they can get too close.
Apostle like Rory and Giselle can slash an Ogre in half with their weapon with little difficulty.
