On the planet Ikra, the Democratic Republic of Zolphir (DRZ) boasts the most military might.

The DRZ, with their Greenlight Legion, is officially stated to have three noble principles: safety on every border, freedom for the helpless, and innovation beyond the flesh.

The Greenlight Legion is made up of volunteer troops and indentured servants who gave their bodies to the machine; the machine that makes weapons out of their bodies.

The greenlights, with their weapons ready, march in drone-like fashion and employ a strength through numbers tactic, painting the enemy's horizon green from the glow of their visors.

Clad in comfortable robes with a simple protective vest, the officers rarely see frontline combat alongside infantries. They are mostly found giving orders from either the command bridge of an elite vehicle or a settlement outpost. Whether they're a captain or an admiral, they wear standardized uniforms that keep their exact ranks classified. This means that when targeting officers, even one still standing could turn out to be the one that has the most warfare at their disposal. Closely observing their patterns and commanding signals is strongly advised before deciding who to take out first.

Within the cockpits of trucks, tanks, turrets, drone transports, or sand trains, the driver unit operates any ground assault machinery. Although they work closely with infantry and often see frontline battle, their armor is among the cheapest and least comfortable in the ranks. It is built only to survive basic crashes, the crudely-welded helmet's protection being especially poor. A driver is typically expected to use their vehicle as their protection, and to remain in it at all times, even if the air inside it heats up. Being sent to drive the tank is often a punishment given to troops that perform poorly on foot. What started as vastly underfunded safety and comfort inside vehicles is now a discipline that officers swear by as motivation for soldiers to power through even the least bearable terrain.
