"This is a waste of our previous battle. We still have no way to break through the Japanese defense line?" Hearing Wang Si's analysis, Jiang Caidie ignored He Guoqing's inquiry and said directly to Wang Si.

"It can't be considered a waste of fighting. We at least forced the Japanese to compress the defense line and gain more depth for our team!" Wang Si said immediately after hearing Jiang Caidie's words, then turned around and said to He Guoqing on the side, "Although we don't know where the Japanese's defense is, where we can hit it with one blow! But the two castles in front of us must be pulled out!"

"Just just now, a reorganized battalion of the 435th Regiment could not rush up, so why can we get through it?" The big man looked at Wang Si in confusion, feeling that the strategic purpose that Wang Si mentioned was simply something that could not be done.

The 435th Regiment had a reorganized battalion and the support of the artillery company, but they could not take down the two castles. How could they? Could it be that their commando team with less than two companies could be more powerful than the 435th Regiment, a reorganized battalion and the artillery company?

This is not realistic at all, let alone if this battle is easy to fight, why would the 435th Regiment give them the credit for getting it? You should know that the leader is a guy who loves to get it and cannot give the price he gets to others. Therefore, he thinks that this battle will not be as simple as Wang Si said.

"The strong attack is definitely not possible, but we can take it out of our mind!" Wang Si seemed to have thought of a solution, so he said to everyone, as if everything was under his control.

"How can you learn from the wisdom?" He Guoqing and Cui Yaolin both wanted to know. The biggest trouble at the moment is that these two firepower points are hidden underground, and there is no way for the bombs and mortars outside to deal with them.

If the team rushed up, it would become the target of the Japanese machine gun. There were countless casualties and injuries, and there was no way to get close. They tried to think of many ways, but it seemed that they could not work.

Now that Wang Si said this, he naturally wanted to know what kind of way Wang Si had to solve this difficult problem.

"Don't we have grenade launchers?" Wang Si said to everyone when he saw everyone's anxious questioning, but he didn't intend to continue hiding it.

"Is the Fourth Brother joking? The 435th Regiment and the others used the mortars in the cannon company. Can our grenade launcher work?" The big man immediately looked at Wang Si in doubt when he heard this.

Compared with a mortar, the stars are brighter than the bright moon. No matter how powerful the grenade is, it cannot be compared with a mortar that is several times more powerful than a grenade. He really doesn't know what Wang Si thought, why did he mention the grenade at this time?

"The use of mortars is to determine the orientation. When the shells are fired, they will fall in an arc. No matter how you fire, the shells will only hit the surface. Even if they explode, they will not be able to harm the hidden firepower underground." Wang Si explained. He knew that there were more than one person who was confused, so he first explained to everyone why the mortars were powerful and could not attack the underground castle.

"There is some truth to say that mortars are only suitable for blowing up large areas of targets. For underground castles that require precise strikes, they naturally seem useless!" Jiang Caidie immediately agreed when she heard Wang Si's analysis.

"But the grenade launcher is different. It fixes the grenade on the grenade device and then pulls the trigger for firing. It can accurately shoot flat. In this way, we can accurately shoot the underground castle and blow up the Japanese underground castle!" Wang Si continued.

Although he is not an artillery, he can gain a lot of experience from commanding his brothers to fight such many battles. At present, these analysis of weapons are the experience he gained from previous battles.

"Each of our company has four grenade launchers. In this way, we can use the grenade launchers in our hands to open the castle that the Japanese blocked in front of us!" He Guoqing fully understood what Wang Si meant when he heard this.

After the main attack of the 435th Regiment, they completely pulled up their distance to the Japanese Burrow. Although it was only a small ten meters, this was enough for them.

"This distance is not a difficult task for our grenade launcher!" Wang Si immediately said, "Old He, you can adjust our grenade launcher to the four doors now. I want them to concentrate their firepower and blow up the Japanese firepower port!"

"I understand, I'll make arrangements now!" He Guoqing immediately said after hearing Wang Si's words, then turned around and waved to the brothers behind him, allowing the four grenade launchers to come to the front.

Of course, the four brothers did not dare to neglect. They immediately came to the front with the grenade launcher, preparing one by one on the side of Wang Si, putting all the grenades into the launcher, and waiting for Wang Si to order to open fire.

"Let me listen to me. I will let a few brothers go over to attract the Japanese firepower. When you see the Japanese firepower outlet, you will immediately hit me according to the Japanese firepower outlet. Be sure to blow up the Japanese's castle!" Wang Si saw that the four grenade launchers were all preparing, and Wang Si immediately told them.

The four grenade launchers responded immediately and then focused all their attention in front. At this time, as long as there was any movement in front of them, the trigger in their hands would be suppressed.

Seeing that the grenade launcher was ready, Wang Si said to the veteran, big man and Ma Sanpao, and the other three: "You three go over and find ways to attract the Japanese to fire!"

"I understand!" Ma Sanpao responded immediately, and then, with the big man, the two veterans crawled towards the front of the castle.

After continuing to approach the Japanese Burrow for more than ten meters, the big man and the veteran first took the Huaji Machinery in their hands and fired at the Japanese Burrow fortress. The sound of gunfire sounded instantly, and rows of bullets shot towards the Japanese Burrow fortress.

The Japanese inside couldn't help it, for fear that the veterans and the big guy would approach the castle, and then used explosives to blow up their hiding place. So the machine gun inside swayed left and right at the big guy and the other side, and the bullets were shot to the ground.

When the big guys heard the gunshot, they immediately turned over and dodged, retreated a few meters behind the stones, hiding behind, and did not intend to look up.

At this time, the grenade launcher brother immediately pulled the trigger, and the grenade inside the grenade launcher mounted on his shoulder flew out immediately, and with the flames that followed him behind, sprayed towards the Japanese shooting hole.
