The Penitent trooper is a unit of Ouroboros. Built to be a cannon fodder/meat shield for the deadlier, but fragile, volunteers.

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. 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.
 * Every wound a mark towards freedom: Armed with a heavy shield and wrist-mounted needle that can damage through infantry and light vehicle armor, the Penitent trooper charge into battle, drawing enemy fire towards them while the volunteers goes in for the kill
 * Dead soldier walking: Penitent trooper are prepared to fight to the death against their foes, and will never retreat even when their morale breaks. And can, with a shot of adrenaline, charge headlong towards their foe, the impact often knocking infantry off their feet and stunning vehicles, while charging into garrisons often kills any foes inside even if it means sustaining lethal injuries in the process, all to atone for their past sins
 * Just an enforcer: Penitent troopers, despite their armor and weapons, are pretty slow and their weapons lacks the power to do much damage. With their role being more of a meat shield to protect the volunteers

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. And 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 or previous career in the military, 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 grazing upon their damaged flesh feels like hot knives flaying their skin.

Once their procedure is complete they became the workers and soldiers for the Government, whether it be guarding a convoy or fixing a ship, and in war are the main soldiers of Ouroboros, their rivet gun capable of punching through flesh just as good as bronze while shrugging off anything short of an autocannon.

Trivia

 * The Penitent trooper suit is based off the alpha big daddy from Bioshock 2.
