Kalran: Tales of the four nations/Aegis Defense Force

Before his final battle Thor, the hero of the Fenrirs, had formed the ADF in secret. Knowing the threat the Reclaimers can become to protect Alcradia.

And since then the ADF is a secret task force, only known by the leaders of the world and high ranking commanders, whose sole goal is the protection of Alcradia and the destruction of the Reclaimers. Their forces, comprising of every race, armed with cutting edge technology, classified to the world, to take on their foes with swift and devastating surgical strikes, taking on forces that always outnumbers them and winning with little casualties.

Tactics
The ADF represents an elite task force, playing more like real time tactics game like dawn of war 2. Each of their units can take on their foes equivalent that outnumbers them four to one and win. Combining speed, power, toughness, and devastating abilities that allows them to steamroll their foes. And with how their veterancy work means a fully ranked ADF units becomes a one man army. And with their crawler, their mobile base, their forces can mobilize anywhere.

But all this power only comes at late game. And in the early game they struggle, due to how expensive and limited their units are, since their cost barely justifies its power and having to rely on universal upgrades and veterancy rank up to edge out their foe, and with their crawler being their only production facility means it also takes time for their forces to be on the battlefield. But if they're power is left unchecked then they will steamroll their opposition with little resistance.

Mechanic

 * Quality over quantity: Due to how expensive it is to equip an ADF unit their the only faction where all their units have a cap, from 6 to 1, limiting their numbers. But compensates by being superior to their equivalent with little weakness. And their units will gain an upgrade, similar to a UCA ace upgrade, per veterancy rank, up to five, alongside a passive increase to damage and health.
 * One base: Their crawler is not only their base but also produces all ADF units and contains all of the ADF upgrades, including superweapons, and can also be upgraded to their epic unit. Being the toughest base out of all the other factions. But in the event the crawler is destroyed they instantly lose
