- Overview[]
The S1 Ulster is the first Tank designed and created in the United Republic Federation, used by both Army and Marine Corps. No exports are currently planned for the Three MBT models.
The Tank was given S1 as the original and the S1A1 as the upgraded variant, and the S1A2 as the Final Variant. With over 3,750 tanks produced, the MBT was able to fill in the additional slots along with giving the Military an advanced piece of hardware.
The Tank was first used during the Evan's Rebellion, then was used in mass by during the Foltest Wars. The simple repairs and maintenance made it possible for reuse.
- Design[]
As the K1A1, M60 and the T-72 tanks come in, the Armed Company was producing thousands of copies for both the Army and the Marines to use. They even took the F-4 Phantom and redesigned it with F100 engines, reducing cost.
Knowing this, the Sharp Industries plans to design an indigenous tank to show off the company's ability to produce their own equipment and mass produce them with perfect quality and quantity.
After studying the K1A1 smoothbore gun, the head design was a redesign of the K1 Tank with some additional items added. The body of the T-72 tank was remade with some changes and modifications, along with its treads using hard rubber instead of metal. Creating the perfect tank they wanted, the XS1-01 and 02.
The "S" on the tank's designation represents the company's first letter of their name. This also shows that the Sharp Industries did create the tank.
Once the prototypes was ready, both tanks was tested against three K1A2s and four T-72Sims. The tanks then went head to head with the K1s, disabling them by shooting before the K1 tanks. Then putting it up against the T-72 tanks, using their Autoloader to their advantage. The only downside to the test, were the jamming of the Autoloader.

The S1 Tank series was soon put into a recommended redesign. The plan was to give it better engine performance, better firepower, better armor, and higher production to retire both T-72Sim and M60A5 tanks. They will also complement the S1A1s, as those models were given an upgraded hull for a newer engine. An A2 variant was developed to give it a normal All Terrain Style, advance Infantry and Armored Support capabilities.
A design was planned with a callsign, A3 Final Series. The MBT was sent out the factory with: 1 x 55 .cal Autocannon, 2 x 7.62mm Anti-infantry machine gun, a 125 mm upgraded Berserker Rifle, and 1 x 30 mm Grenade launcher.
This makes it a multipurpose tank, giving it a anti-infantry and anti-armor weaponry. They then gave it a auto-target system for the machine gun and infrared-red systems to detect stealth vehicles, making it difficult to hide from the new tank. But the Tank was deemed too expensive and repetitive for Federation Forces, resulting in a cancellation of the program. The upgrades were given to A1, who are codenamed A1FU (Federation Urban).
They also gave the latest A1 and A2 models Super Turbo engine, pushing 2,200 - 2,500 horsepower into the vehicle. This makes it goes up to 65 mph, enabling the tank to actually drive on the Interstate Freeway. At the same time, this allows the tank to do hit and runs against other Armored Vehicles. The Gunner seat for the Machine Gun was given a protective glass canopy, keeping the Gunner alive and protected during Urban warfare.
The Sharp Industries has produced over 3,750 S1 Main Battle Tanks from 2019 till 2035, producing over 2,260 for the A1, A2, and Special variants. As each Division are deployed, M60s were decommissioned or put into training units. By 2033, Half of the original S1 MBTs were put into storage.
- Combat Service[]
The Tank was put to the test as 200 S1 Tanks was sent into battle against Rebel Forces, succeeding against all enemy tanks as they attack them. Several Tank battles took place across Occupied Territory, mostly against advanced tanks that never thought up before. But each battle ended with the S1 MBT walking out unscathed.
They were soon put into combat in the late years of the Foltest Wars, going against tanks that scrapped both T-72s and K1A1 tanks easily. One Officer recounted a Battle when his S1 Tank took a hit, "We were under heavy fire, the enemy Tank targeted us after they massacred our footmen, but when he fired, the Tank continued on like it was nothing" he claims.
Once the War was over, the Tanks grew in numbers reaching to 1,000 vehicles. Having them split between the Army and the Marines. During the late years Foltest Wars, Federation Tanks used their advance repair capabilities to stay in the fight. Making them very dependable tanks during the entire conflict.
S1A1FU Urban Tanks training with the URF Army 5th Armored Corp
In 2030, the upgraded S1A1FU and newer S1A2 Tanks are deployed to Argentina. As part of the Intervention of the Argentine Civil War, over 280 Tanks along with 700 K1A2FM are sent with the 25,000 Force. Their most famous actions were in the Eastern Coast of Argentina, where Area CDR. Lucas Thomas advanced near the ocean.
From August 17th - 30th, the Tanks gain over 490 Armored kills and 3,500 Infantry kills. They often are supported by Viper Operatives, Marines, and/or Regular Infantry, along with air support from URF Attack Helicopters or Fighter jets. They only faced a few losses mostly by Rebel Infantry, but the upgraded tanks perform well enough for URF Military Standards.
After the war, the upgrades and modifications are given to some S1 vehicles. While those vehicles are given their upgrades, other tanks are stored as replacements.
By 2033, almost a good portion of the Army and Marine Corp S1A1, S1A1FU, and S1A2 inventory were deployed to West Africa. Most were sent into Nigeria to engaged Borno T-55M and T-62 tanks, eventually were redeployed to Lago Territory against Abrizhouian T-72 and M60 tanks. They also will fight against Royal Abrizhouian Guard's Challenger II tanks, breaking the backbone of Abrizhouian's Armored Corp.
In 2035 - 2038, almost all available models were deployed against Allied Imperial Forces. Fighting on all fronts, from Iceland to Siam to Quebec City itself. Used along side the K1A2, K1A3, T-72Sim2, and Viper Corp K2 Atlay tanks, They lead much of the campaigns across the world. The variants are also modified and deployed during the Korean Campaign, when S5A2 Artillery Tanks shelled military positions in the Korean city of Gwangju. They're also deployed a year later in Siam, shelling the 10 mile mark between Allied Forces and Siam Army positions.
