Having completed its large mobilisation following the Spanish declaration of war and WMD attack on Germany, the Soviet military was eventually in position to begin operations. Delays due to political reasoning in Moscow meant that there were setbacks in the economic front, but the scale of mobilisation, unprecedented in modern Soviet history, was meaning there was no step back now.

Awaiting orders in USSRTactics:
- Tank divisions and Group of Tank Armies race to capture territory

Although the Security Council had drawn up plans for a 200.000-large peace-keeping force contributed by the USSR, Belarum and the Reich, the Soviet decision to initiate it without waiting any further included some 750.000 personnel by comparison - or almost four times the amount originally planned. This was, in part, due to the wartime preparations of the Soviet military, and in part, because the Soviets knew Trierans didn't exactly like them.
Moscow saw this colossal, ultra-expensive deployment of a 750.000-large force of two whole Fronts and a Group of Tank Armies as a temporary measure. The final Soviet contribution to the peace-keeping operations would be 30.000 to 100.000 troops, occupying positions at eastern Triera close to the Soviet border. Until other Security Council troops could arrive, however, the Soviet military was alone in its operation.
Trierans really didn't like Soviets; or at least the more nationalist and anti-communist ones didn't. It took five days to reach the capital due to road blocking, guerillas, and pacifying populations threatening to stop the advancing tanks or disrupt their chain of supply. Losses on either side were relatively low for the scale of operation, with 12 Trierans and 5 Soviets killed, and 60 and 15 injured respectively. The media blackout, however, assured this would not flow out of the Soviet military's grasp.
As the Group of Tank Armies advanced at a rapid speed, stopping only to refuel and approaching the capital in a pincer-like move, the mechanised infantry divisions following it as parts of the 1st and 2nd Byelorussian Fronts were often welcomed with rocks, rioting, or gunshots. Ultimately, pacifying villages and towns along the way would take the establishment of temporary garrisons as well as returning fire to those who opened first.
Five days after the operations commenced, on 7 June, elements of the 1st Group of Tank Armies of the "Trieran Peace-keeping Forces" entered the old capital city of the nation. Positions at the local airport and old government buildings had already been seized by Spetsnaz and airborne troops for a few days now, who had occasionally come under fire by the more hot-blooded of the Trieran population; with the arrival of tanks at the suburbs of the city, however, it meant that all the way to the capital was now open.
Early at noon on 7 June, elements of the 123rd Motor Rifle division entered the centre of Triera's capital. The 1st Group of Tank Armies proceeded to race for the Belarian border and complete the "pre-liberating" of the rest of Triera, followed by large mechanised infantry forces. Old military airfields were quickly occupied by airborne troops or Spetsnaz, and military depots were seized in time to prevent any further looting by possible insurgents.
At early afternoon on June 7, the commanding staff of the operation was entering its new headquarters at the old Trieran Imperial Palace, setting up guard and control over what media still circulated uninterrupted, as well as old government ministries and other buildings. At 5.20 pm, the Trieran radio tower began broadcasting news of the imminent liberation of Triera City by Soviet military personnel.
"People of Triera! A new dawn has come for your motherland and homes, as military forces of the USSR have entered and seized control of the Trieran capital from anarchy and disorder! Your Soviet friends, determined to assure Triera's continued survival, shall immediately undertake the task of forming a new and independent Trieran government for the benefit of the glorious Trieran people. Until a cabinet is formed, the military authorities shall hold all power with the aim of protecting and defending the Trieran people."
