In the cramped electronic early warning aircraft soaring in the sky, the Tang Army's dispatch personnel complained while staring at the radar screen: "Commander! There's too much ground clutter! We can't distinguish the enemy planes flying close to the ground from anything else."
"How about at high altitudes?" The commander behind him rubbed his tired eyes and asked, "Have any enemy planes appeared?"
"So far, no enemy planes have appeared at high altitudes. Our fighter jets are patrolling in Zone 4 and Zone 2." The dispatcher looked at the signal feedback of friendly aircraft on the radar screen and reported to his commander.
The Dwarves launched a large number of propeller aircraft, flying close to the ground attempting to cover the ground troops in combat. These aircraft have a small radar cross-section and aren't fast, allowing them to fly low and evade the Tang Army's early warning aircraft detection.
