Kalran: Tales of the four nations/Heimdall

"Feets greased! Guns loaded!"

Tactical analysis

 * Stalwart guardian: The Heimdall battlesuit has been designed with only one goal: to stand their ground. Armored in heavy, but incredibly sturdy armor, making them the toughest infantry bar none, and two large plasma missile launchers capable of ripping apart any forces, whether air or ground, and a chest-mounted stun beam, completely freezing an infantry squad for their missile strike, or allies to attack
 * Stand firm against the tide: If needed the Heimdall and plant themselves to the ground and activate their defender field, inspiring surrounding units to fight harder while healing them and granting cover, while allowing the Heimdall to fire their missiles at a faster rate and increasing their beams output, now stunning surrounding infantry too
 * The immoveable object: If ever faced with something that can break them they can deploy a super shield. A powerful dome capable of stopping almost anything, but will temporarily render them immobile and will break under concentrated fire
 * Slow and steady, may not be enough: However they are rather slow, as fast as a standard MBT, while their bulk means that they barely fit into the Bifrost, and their missile, while devastating, have a rather low rate of fire
