Goguryeo's Armored Cavalry (Gaemamusa)

One of the secrets behind Goguryeo's dominance in Northeast Asia was its formidable heavy armored cavalry, known as 'Gaemamusa'. 'Gaema (鎧馬)' literally means 'armored horse'. These warriors, along with their mounts, were fully clad from head to toe in steel armor. Thanks to this, most enemy arrows or spears couldn't inflict significant damage. When battle commenced, the Gaemamusa, clad in heavy iron armor, would charge at the forefront into enemy lines. This charge possessed immense destructive power, akin to modern-day tanks. Behind King Gwanggaeto the Great's relentless territorial expansion lay this elite force, united by superior ironworking technology and bravery.
