The units shared with the Soviet Union were: riflemen, engineers
1> Rocketeer
Allied units, the Soviet Rocket Force can only be used in multiplayer games, and occasionally appears in campaigns
The Rocket Force is equipped with Ceramic and Red-Eye missile launchers, Tao against tanks, and Red-Eye against aircraft and submarines, which are a great threat to submarines, helicopters and light vehicles. Missiles are difficult to hit moving targets and are extremely weak against infantry. They move slowly, have lower defenses than riflemen, and are easily killed by grenadiers, as well as mammoth tanks. As a cheap anti-carrier class, they single-handedly lost to Allied gunboats and Jacques attack aircraft. The Rockets also worked well against the buildings, outpacing Allied machine gun bunkers, camouflage bunkers, and Soviet flame towers. After the war, the Rocket Soldiers were all retired.

Other games
In the First Tiberium War, both GDI and NOD had Rocket Force;
In Red Alert 2: Yuri's Revenge, the Rocket Soldier is replaced by a heavily armored soldier.
2> military doctor
Military medical training is expensive, professional medical training, and has a full range of medical tools to perform surgery on the battlefield. Because the medical kits were heavy, they moved slower than the riflemen and were unprotected and unarmed. Their uniforms are the same as those of riflemen, but they are equipped with Red Cross armbands that automatically heal wounded soldiers within a certain range. After the war, the medic retired.
In the First Tiberium War, engineers and technicians of GDI and NOD could treat friendly forces with healing guns;
In Red Alert 3, Allied engineers can set up first-aid tents.
3> spy
A spy is a British agent who is proficient in imitating the habits, language, and behavior of enemy riflemen, can infiltrate enemy bases without being discovered, can perform reconnaissance and infiltration of buildings, and no one but military dogs can spot him. The spy is slow and does not carry a weapon, but in the cutscene the spy has 2 pistols.
The role of spies infiltrating different buildings:
1. Base, barracks, chariot factory, shipyard: display the current production unit;
2. Submarine Manufacturing Plant: Displays the units currently produced; provides "sonar pulse" skills to scan the position of enemy submarines;
3. Apron: displays the units currently produced and displays the amount of ammunition on the current landing aircraft;
4. Airport: Displays the units currently produced and displays the amount of ammunition on the current landing aircraft; provides "bomb" skills;
5. Power plant: display the amount of electricity;
6. Ore refinery/ore warehouse: display capacity indicators and the amount of ore currently held;
7. Radar station: display the position of the troops;
8. Fake building: revealing the real body
Sonar pulses
bomb
Espionage is used in Red Alert 3, where the function is merged with thieves to steal money from enemy ore refineries, invade power plants and cause power outages to paralyze enemy base defenses, etc.
4> Thief
In the face of the powerful offensive of the Soviet Union, the Resources of the Allies were increasingly scarce, and they had to resort to guerrilla warfare and steal Soviet resources to support the battlefield. The thieves are agile, without weapons or protection, and they wear hats, tuxedos, and cloaks in the game, and resemble Zorro; however, the game icons are obscene. He can enter enemy ore refineries and mines to steal half of the building's resources.

In the final attack on Moscow, several thieves acted with Tanya. The Molotov brothers, who were secretly allied with the Allies, often transported thieves in the APC. The thief retired after the war.
In Red Alert 3, thieves are replaced by spies
5> Field Mechanic
Appears in the expansion pack Red Alert: Aftermath
In order to prolong the survival of the armored division and maintain the momentum of the offensive, the Allies trained field mechanics, who moved slowly, did not carry weapons, and repaired vehicles on the battlefield. Embarrassingly, if a field mechanic were to get into an injured APC, he would have to completely repair it first. Field mechanics repair even much faster than repair shops and don't consume resources. When faced with MAD tanks, field mechanics can quickly regain the combat effectiveness of armored units. After the war, the field mechanic was retired.
In the First Tiberium War, the service guns of engineers and technicians of GDI and NOD could repair vehicles;
In Red Alert 2/3, engineers enter the IFV to repair the vehicle
6> Tanya. Adams
Tanya was a civilian, an Allied mercenary, not enlisted; General Gunter von Esling, who sheltered her because she was a powerful agent, was deeply disrespectful of military authority: when General Nikos Stavros expressed concern about her civilian status, she interrupted him with the words "that's why I wasn't killed." The only reason she didn't drive away was her powerful skill.
Tanya's birth experience is magical, her creator Adam Isgreen is obsessed with Wu Yusen's action movies, and created this female agent with a double pistol.
Tanya is expensive and can be trained by the Soviet Union in multiplayer battles, she is very good at dealing with infantry, and the C4 is powerful against buildings, but she is powerless against vehicles. She can also be killed and crushed by a military dog, and worse, Tanya will not automatically fire unless attacked, so she is very passive against the military dog. Tanya was initially paired with the former IRA Meghan, who was later killed.
Under the command of field commander A9, Tanya rescued Albert Einstein from a Soviet research facility and subsequently blew up key bridges for the Soviet offensive in Eastern Europe. Later tanya was captured, general Gunter von Esling ordered the field commander A9 to rescue, the spy was stabbed by the executioner while rescuing Tanya, but threw the pistol to Tanya, then he killed 6 anti-aircraft missile guards and evacuated in a Chinook helicopter. She brought intelligence to the Allies about the Soviet "Iron Curtain Project."
When the Soviet Union fired 4 nuclear bombs, field commander A9 commanded Tanya and other troops to infiltrate the Soviet ballistic missile control center and shut down 4 nuclear missiles. She then stole funds from outposts near Moscow to establish a base for field commander A9.
During the counter-offensive against the Soviet Union, Tanya protected General Nikos Stavros from Greece, which had been attacked by the Soviet Union.
During the Soviet campaign, Tanya infiltrated the Soviet interior and tried to shut down the nuclear reactor to delay the Soviet offensive, and was killed.
