Set in 2035, when the Vietnam War is still ongoing, the Eastern conflict and Russian troops are equipped with Iron Harvest technology.

In the year 2035, amid the grinding conflict between the Eastern Bloc and Russian forces while the Vietnam War still rages, the elite 4th Armored Battalion of the Saunders Expeditionary Force is led by the bold and charismatic Captain Kay, whose trademark M1 Abrams spearheads every advance with aggressive precision and unshakable optimism. At her side is the sharp-eyed Lieutenant Alisa, the battalion’s master of electronic warfare and reconnaissance, whose calm intellect and ruthless talent for intercepting enemy communications turn the desert battlefield into a web of calculated ambushes. Completing the command crew is the steady, deadly accurate gunner Sergeant Naomi, whose cool focus from the Abrams’ turret has never missed a critical shot. Together, the three women and their armored spearhead are tasked with a vital peacekeeping operation: racing through the southern route of the eastern desert to intercept and stop a heavily escorted Vietnamese armored convoy before it can deliver vital oil supplies to Russian forces.
