I did not understand why I should do this if everyone uses a non-stop stream of T1 scouts on the ground against Cybran and on the water against Cybran sonar.
Also, when naval attacks, it is visible until the ships of the defending-retreating sink, all ships have a vision + sonar + underwater vision. And the ships sink for a very long time.

The scout (or any other air unit) continues to be shown visually and the radar will not fall to the ground. Also, the ships will not sink yet, they continue to transmit vision and sonar until they reach the bottom.
Is it possible to stop showing vision after the death of the unit?
Too much is counteracted by the T1 scout, as well as the naval battles.
Or after the death of a moving scout, he began to feed not in the direction of movement, but down or with a decreasing coefficient to his speed, for example 10%.
