Kalran: Tales of the four nations/Penitent trooper

Tactical analysis

 * A chance for atonement: Made from criminals, or even those against the governments rules. The Enforcer are the basic penitent soldiers of the government
 * Dead woman walking: Fused to armored diving suits. The Enforcer armor, and numbness towards pain, makes them on par with other heavy infantry, capable of shrugging off small arms, but the weight of their suit makes them slow and unable to swim, but they can simply walk underwater. While their rivet gun and wrist-mounted needle can punch through infantry and tank armor
 * Wrath and ruin: Enforcer are prepared to fight to the death against foe, and are immune to morale damage. And against garrisons they are known to rush headlong into it, killing any foes inside even if it means sustaining lethal injuries in the process, all to atone for their past sins

Overview
The Enforcer are those who defied the Government. And as punishment their body is, sans their head, is fused to their armored diving suit, which is based of the Alpha big daddy from bioshock 2.

History
The Enforcer are the basic penitent soldier, consisting or Nekomatas with an higher aptitude in strength, but unlike the other penitent soldiers they are the only soldier that can remove their helmet, though the modifications they go through means that even a breeze on their bare skin feels like burning knives.

Once their procedure is complete they became the guards for the Government, whether it be caravan, convoy, or a noble, and in war are the main soldiers, wielding a cannon that fires heated bronze rivets while shrugging off anything short of an autocannon.
