Kalran: Tales of the four nations/Penitent charger

Tactical analysis

 * The ripper: Armored in the heaviest combat suit. Penitent chargers can take on infantry and tanks, ripping them apart with their high powered drill, while its large bulk allows them to crush regular infantry like a tank
 * Cutting off the juice: By cutting off their secondary drug system results in the charger going into a violent outburst, causing the to to charge with greater anger into nearby targets, flipping light vehicles and splattering infantry with its great strength. But the commander will briefly be unable to control them
 * Hold on: Penitent chargers, when not cut off from their supplies, are rather slow and this, with their limit to melee range, means they are vulnerable to long range and aircraft
 * Jack me back in: In time, and showing their compliance to fulfilling their debt, the exact mixture of drugs to keep the charger at maximum possible pain without compromising performance can be discovered. When this happens, extra pain is not even registered by the charger, making them charge faster, immune to suppression, and killing a target now causes nearby infantry to cower in fear. Alongside this they are also trusted with a prototype harpoon drill, which is enchanted with ice and blood magic. But this has to be calibrated to the individual, though, and the risk of the user using their newfound pain and weaponry to attack the volunteers means that it's only limited to a few soldiers
