The Tang Army's airplanes were extremely fast, and their attack method was no longer the traditional bombing, but instead a barrage of rockets.
As a result, the Qin Army's anti-aircraft troops were completely unprepared for such an attack. They could only watch helplessly as the Jian-6 roared away, leaving behind havoc on the ground.
In reality, the Qin Army didn't suffer heavy losses, which was true. As a fighter jet temporarily adapted for ground attacks, the Jian-6 was really quite inadequate.
Although it was equipped with rocket launchers for ground attacks, its attack accuracy depended purely on faith. Its air combat gunsight was not designed for ground attacks, and the dispersion of the rockets was far from any so-called accuracy.
The lightning-fast attack looked intimidating, but in fact, once the Jian-6 had flown away without looking back, the Qin Army on the ground found they had lost almost nothing.
