1> sonar pulse
When Allied spies infiltrate the Soviet Navy dock, they will be horrified into the navigation system of enemy computers, and the player can obtain a sonar pulse skill, which can briefly display the location of all enemy submarines on the map.
2> GLOBAL POSITIONING SYSTEM
During World War II, the Allies developed the ultimate means of reconnaissance: the Global Positioning System. After the player builds the Technology Center, the technician will launch a medium-orbiting Earth satellite to dispel the fog of war and display all enemy units.
The world's first satellite launched by the Allies in the game's cutscenes is actually Sputnik Satellite 1, which was launched on Soviet R-7 series rockets, the latter two being the world's first intercontinental missile/rocket and the first artificial earth satellite (Westwood and Oolong).

3> time-lapse teleportation
When using time-space teleportation, there is a small probability that a time-space vortex or even a space-time earthquake will occur. It cannot transfer nuclear bombs (self-detonating trucks), can only transfer one unit at a time, and cannot be used against enemies. It can't teleport infantry, even if it's in the APC, but it doesn't include drivers. The unit being teleported returns to its pre-teleport position after a period of time.
4> nuclear bomb attack
Both the Allies and the Soviet Union possessed nuclear bomb silos, and the Allies did not use nuclear bombs in the campaign, only in multiplayer games. This tactical nuclear warhead is equivalent to 2,000 tons of TNT explosives and can attack any location on the map.
