Kalran: Tales of the four nations/Adamantclad

"Adamantclad ready to send them to the depths!"

Tactical analysis

 * A undersea tank: Essentially a Doberman if it was a submarine and armed with four massive guns, quad AA/point defense autocannon, a rack of high-powered rockets built for heavy AA and coastal bombardment, and large reserves of health, the Adamantclad capital submarine can decimate enemy vessels in direct combat
 * Send them to the graves: In their zeal, Adamantclad captains have been known to overload their subs weaponry as they lay waste to the Volksgard enemies. In doing so they substantially augment their submarine firing rate, though the launch mechanisms sustain electrical and mechanical damage in the process. By that time, however, there is usually no enemy left to fight back. Though the crew are also skilled in repair, meaning that once the captain stables their system the crew can begin repairs
 * Can't escape davy jones: Similar to the Doberman the Adamantclad can fire a void beam to hold and slowly drag enemy ships or vehicles into range of its guns, or even to the depths for vehicles. But to maintain the beam the Adamantclad must become immobile, and can only turn at most
 * Come and face me: However the Adamantclad is severely slow, like the Doberman, and its weapons range, except their inaccurate rockets, are equally short, necessitating its ability to submerge to close in, and while its autocannon and rockets can handle aircrafts they are rather below average in their role, meaning that numerous and/or strong aircrafts with anti-submarine weapons can easily sink them if they go in without AA escort
