“Rhino Horn” emphasizes its defensive and impact‑resistant horn design, while “Fortified Trooper” hints at its role as a mass‑produced, positional-defense mecha. A relic of the old era’s frontline defenses, its armor surface bears the weathered marks of battlefield wear and tear; its horned extremities can house energy cores capable of deploying protective barriers. By substituting the more common term “Warrior” with “Fortified,” the name underscores the unit’s niche tactical focus on static, fortified defense.
