When attacking an enemy bunker, will shooting into the shooting hole or bullets entering the shooting hole happen?

In some TV dramas, we often see buildings made of reinforced concrete. This kind of building is called a "bunker". It can be said that the bunker is indestructible and can withstand enemy guns. and artillery shells to defend against enemy sneak attacks and attacks. At this time, some people thought that the bunker was not fully enclosed, and that the bunker also had some channels to communicate with the outside world. Therefore, when attacking a bunker, is it possible to shoot or drive bullets into the shooting holes in the bunker? So far, this question has been an elusive one.

Admittedly, the probability of getting into the bunker's shooting hole or getting a bullet into it is very small. Because the bunker is a very important fortification building during the war. During the early stages of construction, various issues were taken into consideration. Therefore, bunkers in reality are generally in a figure-eight shape. The defending bunker can observe the dynamics and conditions outside through the shooting holes, thereby accurately judging the local situation. As the saying goes, "eyes see six directions, ears hear all directions", you can grasp every move outside in the bunker, observe the enemy secretly, and annihilate the enemy in one fell swoop. ?

Bunkers are generally built differently on different terrains. For example, on flat ground, the bunker is built according to the flatness of the terrain. Another example is in a place with steep terrain. Such as a mountain, then bunkers are usually built against the side of the mountain. Since then, the guards on the side of the bunker have had a great advantage. Not only can they hide and protect themselves well, but they can also catch the opponent by surprise with lightning speed. Since then, the side defending the bunkers has had the upper hand in terms of time and location. ?

However, attacking the enemy's bunker cannot be carried out blindly, nor can it be attacked solely by relying on brute force and firepower. Because this method is generally not feasible and the success rate is very small. It is difficult to cause fatal damage to the enemy. However, during the Anti-Japanese War, our country used wisdom when attacking Japanese bunkers, burning straw and creating smoke and fog, forcing the Japanese army to flee in panic.
