The Legonair X is an improved version of the original Legonair, unlike its older brother it is armed with an actual plasma cannons, and the 30mm heavy machine gun has been replaced with a more effective 30mm plasma autocannon, while it seems strange to still include an ammo racks, this was done to store the energy cells that the Legonairs main gun uses to be sadly put away in a safe location, its armor is invisible to heat seeking optics, and can become invisible if needed, it has a now fire control system and a new AI that helps the crew to make decisions, tell information, and tell apart if a tank is an enemy or not, while still using a loader, it makes up for this with new tech.
