If your reconnaissance forces failed to discover the enemy, then everything in that area would be pitch-black to you. Satellites could also conduct detection, but depending on the type of satellite, there would be a certain delay and potential for misjudgment in locating the enemy.
For example, your satellite might scan the area and detect only a battalion, when there was actually a regiment stationed there.
After all, satellites were not omnipotent.
Moreover, satellites had limited windows of operation. Military satellites were not in geostationary orbit. Even if they had orbital maneuvering capabilities, they could not remain over one area indefinitely. The time they could monitor was limited.
Once that time passed, your map would turn pitch-black again.
Now, people in five different locations were quietly waiting for the final countdown to end: Principal Zheng's group, the dozen or so generals in the observation hall, Professor Wu's group, and the others.
At this moment, however, Professor Wu and the others were more concerned with the stability of the program's operation. He did not care at all about who won or lost. He only wanted to make the entire program more complete and refined.
Then there were Jiang Yan Hai and General Hu Shaofei.
Jiang Yan Hai quietly watched the countdown before him. The instant it ended, he spoke. "All units, conceal yourselves and assume defensive positions where you are. Satellite system, scan the enemy satellites at full capacity. Calculate their positions and orbital paths at full capacity."
Their satellite detection results would not come online until three minutes later, but that was because the satellites would only arrive above the target area three minutes later to provide battlefield intelligence support. It did not mean the satellites could not be controlled from the start.
In fact, all the satellites in their
