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 Penitent trooper are the basic penitent soldiers of the government
 * Dead woman walking: Fused to armored diving suits. The Penitent trooper 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 wade underwater. While their rivet gun and wrist-mounted needle can punch through infantry and tank armor
 * Wrath and ruin: Penitent trooper 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
 * This is a drill: Troopers who went through theatres of war, showing their devotion to atonement and little thought of rebelling, are known to be to be trusted with having their wrist blade replaced with a drill and the rivet gun upgraded to fire superheated rivets, burning the target upon impact afterwards

Overview
The Penitent trooper are those who defied the Government. And as punishment their body, sans their head, is fused to their armored diving suit, which is based of the Alpha big daddy from bioshock 2. Underneath their helmet they are bald, and their face partially rotting and covered in an array of scars, with the most noticeable being a huge lobotomy scar.

History
The Penitent trooper 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 a breeze on their damaged flesh feels like being lit on fire.

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 bronze rivets while shrugging off anything short of an autocannon.

Ace upgrade
