Author's Note

I will add more nations joining in the battle against the Everyfree Army and the Griffon army. I just need some time to develop the plot some more. Criticism and suggestions are allowed so I can do better. Also, I listened to this song while I wrote this. Hope you enjoy it.

Soviet Storm

Battle for Ponyville

Captain Sieger's troops fortified the areas around Ponyville ready to defend it from the Everfree Army made of Changelings. The Griffon army was forming up on the right flank while the Everyfree Army positioned their troops on the left. It was a pincer movement. Captain Sieger signaled his men to defend.

The Griffons charged and broke through the Equestrian defenses. Sieger's soldiers were just new recruits. They were assigned to be in the 1st Royal Guard Brigade. They were no match for the battle hardened Griffons. The Griffons continued the onslaught against Sieger's Brigade. There were too many losses and the Griffons had the upper hand now.

Suddenly, they heard a thundering sound in the east. They saw steel machines rumbling through along with biped creatures riding them. The Soviet Storm swept through the ranks of the Griffons and the Changelings with a few KV-1's and a handful of T-34's. The Soviets rumbled away after the battle was over. The ponies were confused of what just happened. The 1st Royal Guard Brigade went back to increase their defenses while Sieger filed a report on the strange encounter to Celestia.

Battle of Manehattan

General Star Fire and his 89nth Royal Army were under siege at Manehattan. They were being attacked by the Shadow Bolts and Changelings. The Changelings were infiltrators disguising as the opposing foes and then attack causing friendly fire among enemy ranks. The Royal army and the changelings bitterly fought over each block of Manehattan. The Shadow Bolts were like flying archers pinning down the 89th Army soldiers. Building after building, the 16th Royal Reserves Regiment engineers were building barricades to reroute the attacking Changelings.

After hours of fighting, the two sides heard buzzing sound and saw a squadron of flying machines firing arrows of their own. What they saw were YAK 3's and IL 2 Sturmoviks. These planes were part of the USSR's air force. Following the birds of prey, Rumbling was heard behind one of the barricades, behind them steel infernos burst through and engaged the Changelings. The tanks were IS 2's and KV 3's accompanied by ZSU 37mm AA tanks shooting down the Shadow Bolts. The Infantry accompanying the tanks charged at the enemy regardless of their capabilities. Star Fire saw that these creatures weren't afraid of death and were rushing towards the enemy spraying them with their weapons. He saw them take a few prisoners and the leader seemed to shoot them even if they were captured. The Royal Guards saw that these creatures tortured their enemies and burned them alive. One of them stuck a red flag bearing a hammer and sickle symbolizing industry of the Soviets.

Soon enough, the Soviets left the city of carnage with the flag of Mother Russia standing at one of the city squares. The Royal Guards prepared for another attack. Star Fire needed to tell Princess Celestia about the new creatures and wrote down everything he saw and knew about them on a piece of paper.

Celestia's Palace

A pegasus delivered Celestia two letters from Captain Sieger and General Star Fire. She read the letters and saw that the two reports claimed seeing the creatures dubbed the Red Army because of the red stars on their machines and caps.\

"These new creatures seem interesting," Celestia said.

She wrote a letter to Twilight about meeting the "Red Army" as the Equestrian Royal Guards needed all the allies they could get. The Princess had faith in her student about meeting the Reds. She read more and more of the combat reports from the fronts of Equestria.

Ponyville

Twilight received Celestia's letter and gathered the other elements.

"Ok girls, we have been tasked on looking for the mysterious Red Army," Twilight explained to the others, "We need to make contact with them and let them join our alliance."

"How do we find them and what do they look like?" Rainbow Dash asked.

"Celestia said that these creatures wear winter coats with a red star on the cap and have machines that outmatch anything in Equestria,"Twilighte said, "These creatures leave a trail of dead Changeling, Griffons and Shadow Bolts in its wake, if we could find a trail, we could find them."

Everyone gulped. They knew that following a trail of slain enemies would be dangerous as they would be vulnerable to any attack. Twilight asked Captain Sieger to have a few of his guards as an escort. Soon, they embarked on a journey to find the Red Army. Twilight looked at her map and saw a trail of slain foes leading towards the mountains not far from Ponyville.

Soon, the trail of dead enemies ended, they saw long rectangular indents in the grass and followed it to an outpost. There, they saw a fence with twisted pieces of metal and saw tents and large warehouses that stored their machines. Also, they saw a barracks housing the soldiers. In the front, there were two concrete structures with small slits to fit some sort of barrel. It must be their headquarters.

"Hello, is anypony there?" Twilight asked.

There was no response.

"Hello, I have a message for you,"Twilight said.

Then, a large creature walked at the gates and saw a highly decorated outfit with about 16 medals. He was silent and signaled his troops to search the ponies. The soldiers took the letter and the leader read and nodded. He would join Equestria's struggle along with his army. He soon shouted orders to his men who immediately did what he asked. They brought a T34 tank with them in which he jumped in and the tank rolled out followed by the other tanks and soldiers. The tide of the war was soon going to turn.

Battle of Canterlot

The Russian tanks rumble to Canterlot and saw that the Shadow Bolts were attacking along with the Griffons. The ZSU 37's fired at the sky filling it with black flak clouds and obliterating the Shadow Bolts as each member gets gibbed by a single AA shell. The T-34's rumbled towards the city of Canterlot and the Sturmoviks started strafing the streets of Canterlot killing the enemy ground units and the tanks sweep in and kill all the remaining targets. Artillery pounded the enemy reinforcements wearing down the main force, so less enemies will reach the defenders. The Griffons and the Everfree army sent in all their reserves as a final assault.

The enemies charged while the Soviets made use of snipers picking off enemy officers and important targets. The T-34's pounded them with high explosive shells. The Royal Guards supported the Soviets in the push back. They managed to create a defensive line around the main palace. Many of the Guards used whatever they can to create barricades to set on fire to redirect the opposing forces. Soon, the air was filled with Griffons dropping improvised explosives and rained hell on the Soviets and guards. The Soviets managed to fight back with the ZSU 37's while the Guards began building up their AA defenses. The ZSU's managed to shoot down at least 200 Griffons down in 5 minutes. Hours of being bombarded, the skies were finally clear. The siege of Canterlot has been lifted but at a heavy loss. The Soviets packed and went back to their Headquarters.

The Guards learned that they needed solid air defenses and had set up ballistas with large depression angles to fit its purpose. It was a multi purpose defense so it used explosive projectiles. Soon, Canterlot was being defended using these new weapons. The Royal Guards didn't need anymore help from the Soviets with their Air Raids. They were ready to take the fight into their own hands.
