Why didn't the enemy throw grenades at the beginning? Because the distance was a bit far, and then there was glass on the windows, and the doors were closed, so it wasn't easy to throw grenades into the house.
But now, the glass on the windows was broken, the door was opened, and then the rocket launcher, which was prepared as a breaching weapon, was accidentally fired and missed, so it was normal for the enemy to throw grenades at this moment.
And indeed, someone did throw a grenade, but Francisco closed the door heavily.
With a thud, something hit the door panel, and then immediately outside there was a loud boom.
The noise was loud; the grenade had exploded outside the door.
Gao Guang moved a few steps to the side, squatted down, then he suddenly stood up, swinging his pistol rapidly, but he didn't find any targets to shoot at.
Trained people are different.
