Uriyangko's attention had been fixed on Gao Yang and his team. After receiving ballistic instructions and confirming the most likely hiding places of the enemy, he immediately fired two rockets.
Although the enemy sniper was hidden in the fortifications and Gao Yang and his team's bullets were unlikely to hit, the presence of the helicopter changed the situation. The two rockets were fired directly into the engineering housing with solid walls but an unfortified roof, exploding inside the building.
With the two rockets fired, everything was settled, and Gao Yang was confident they had just taken out a Holmesny sniper, or even an entire fire point.
The reasoning was simple, if it had been a middle-caliber AK47 round, or the British 5.56 mm bullets, even if Frey was hit, he wouldn't have fallen, because the impact was not that severe.
