Kalran: Tales of the four nations/Kolkov

"Gatling cannon ready!"

Tactical analysis

 * Old but reliable: While rather outdated, being a mk 1, compared to its contemporaries. The Kolkov is still a deadly mech capable to mowing down anyone who nears it
 * This is my weapon: It's power, and reputation, comes from the mechs main weapon. A high-power gatling laser cannon that suppresses and shred aircraft, infantry, and light vehicle in a flash. While the blast of lights disorients those driving in heavier vehicles
 * More power: If the Kolkov is ever faced with a swarm of enemies or a tough unit the pilot can divert almost all of their systems to powering the cannon, allowing it to fire at such speed and power that even tanks and heavy aircrafts melts to slag. But the pilot must stop firing a few seconds later in order to cool down their cannon, lest it melts from the heat
 * I'm going as fast as I can: But with such power the Kolkov carries a rather large pack that severely weights it down means that its slow speed is noticeable and they must take a few seconds to turn their cannon, making them deathly vulnerable to flanking

History
"You shall not PASS!"

When word of the hyperion cannon came, a weapon that can wipe out a city, the human began to build underground vaults in the mountain to protect themselves. And while they survived it came at a cost.

In the later years they began to notice their birthrate had dramatically dropped and, with analysis, realized the ensuring fallout had rendered them almost sterile. And with this realization, knowing that this will lower their chance of passing down their bloodline memories, began focusing on ai and mecha technology, both which they already had basic knowledge even before the vaults, and focusing on improving their mark 1 "peter" tank, a walking tank used in the third age, and went into isolation, to the point the other races thought they went extinct, but when the Reclaimer came to conquer the northern mountains in the 5th age what they saw shocked them.

What they met was an array of laser turrets ripping their infantry apart and missiles shattering vehicles, and when the dust settle out marched a machine, 16-foot tall, and when they fire everything just bounced off it and anyone who came close are electrocuted. and upon firing the survivors scattered. And with that the other races met the humans again.

What the Reclaimer had the misfortune of seeing was the mark 1 "Kolkov" combat mech. built so that the humans can fight in battle with reduced risk of dying. A mech made with the then prototype aether shield, which even a bomber strike won't break, with the pilot inside a a piloting pod that will eject once the mech sustains heavy damage. And are given a high powered "buzzsaw" gatling laser cannon, capable to reducing almost anything to ashes, and a giant pack, which contains both energy cells and liquid nitrogen, to power said cannon
