Kalran: Tales of the four nations/United Columbia Alliance Armed Forces

When the hyperion destroyed Arcadia back in the third age the surviving Fenrirs, or earthborn, west of the capital and the remnant of their army fled west, through what was once a frontier. Where their face reclaimers hunting them or raiders trying to survive. It's people hardened by the experience, where it was common for them to bear arms first. Until they reached the skyset mountains

There, exhausted and near death, the Skarnops, ratfolks who the Fenrirs only knew through trade, were the first to came with a helping hand, giving them supplies and guiding them to an area to settle. Touched by this kindness the Fenrirs welcome them as allies.

And so the years go by and soon they met the Goliaths, hardy mountain folks, while trying to mine higher up. Where war over territory nearly broke but diplomacy prevailed. And soon they meet the Harpies, who had helped miners trapped in the mountains or dropping goats high up the mountain when famine came. And in a few years the four races signed a declaration of alliance and became the UCA.

And with the eighth age they are now the superpower of Alcradia. Armed with the latest weaponry and vehicles and their feared airforce.

Tactics
One thing that is known about the UCA is that they are a flexible force, bending but never breaking. With their tanks smashing through their foes line while infantry guards their flanks and airforce conducting sorties. As a jack of all trades they start out weaken compared to the other factions, forcing them to be on the defense in early to mid game, especially with how their unit veterency works. But once they get to late game and unlocks their stronger units they will become a master of all and will, unless facing other UCA or ADF, steamroll their opponents.

Commanders

 * Classic: Combined arms commander Thomas (Able battalion). Voiced by Colin Hanks
 * Airforce: Airforce commander Jessabelle (Echo battalion). Voiced by Kelly Baskin
 * Defense: Support commander Williams (Fortress battalion). Voiced by Billy Kametz
 * Infantry: Infantry commander Rosalind (Rose battalion). Voiced by Tabitha St. Germain
 * Armor: Tank commander Ronald (Thunder battalion). Voiced by Clancy Brown
 * Communications officer Wallace (announcer)

Mechanics

 * Veterancy: As the Fenrir fights their units become veterans in battle, with a stark difference between a rookie and their ace counterpart. But the loss of a veteran, especially an ace, will hurt
 * Base tier: Due to military rules the commander must requisition the use of the UCA heavier armament, from railguns to power armor, in tiers. While fast comes at the cost of their army being rather predictable
