Just when Liu Hai and Cowan were in front of the sixth position, Van Vliet gave an order to the American army, that is, to eliminate the Chinese tunnel troops on the Shangganling position as soon as possible! The reason why this incident alarmed Van Vliet was because the tunnel troops of the Volunteer Army were reorganized.

In order for the tunnel troops to play a greater role, under the arrangement of Commander Qin, 17 platoon-level political workers and military cadres were dispatched to sneak into the No. 1 tunnel on the high ground under the cover of night, conveying the military division's operational determination to adhere to the tunnel, and establishing a tunnel party branch for unified leadership. All the troops in Tunnel 1 were assigned to the 8th Company, which was commanded by the 8th Company Commander. Then, under the leadership of the tunnel party branch, the tunnel was managed and rectified, so that the tunnel troops formed a strong fighting group!

As soon as it got dark, the tunnel troops organized small detachments to attack, bombing bunkers and touching sentries, causing the US troops to be full of soldiers and trees and have no peace at night. In particular, under the command of the instructor of the No. 4 Company, the troops in the No. 2 tunnel organized many night raids during the 14 days of persisting in the tunnel struggle, seriously threatening the US troops. The biggest result of the battle was that a regimental commander of the US army went to inspect the position, but unfortunately coincided with the night attack of the tunnel troops, and as a result, the regiment commander of the US army was beaten into a sieve!

In order to eliminate the tunnel troops, the Americans tried their best to shoot at close range with recoilless guns; blasting with * packs; Throwing into the pit*; Even the planes were used to dive and strafe at low altitudes, but under the stubborn resistance of the tunnel troops, the Americans' tricks were thwarted! However, the commander of the US army forced the division commander, the division commander forced the regiment commander, and in the end, the commander of the US battalion who had no choice came up with a solution, that is, to let the South Koreans do it, on the grounds that the South Koreans were also Orientals, and the thinking of the Orientals had something in common. The commander of the U.S. Army agreed to this plan and sent a South Korean regiment to destroy the tunnels!

After this South Korean regiment came up, it really came up with a lot of ways with the thinking of the Orientals, using mortars to shoot at the mouth of the pit; smoked with sulfur bombs; plugging the hole with boulders; Blocking the vent with a clump of barbed wire; The South Korean military actually blew up a tunnel of more than 30 meters from the top of the tunnel by means of drilling holes and charging and blasting from the top of the tunnel, causing great difficulties to the tunnel troops. However, the tunnel troops were restricted by the tunnel, and they could not go out to counterattack during the day, so they could only have limited ways to resist, and in the end there was really no way, and the tunnel troops asked for artillery fire to eliminate those enemies who were specifically responsible for destroying the cave entrance, so as to support the tunnel troops to persist in fighting!

Commander Qin and his staff felt that only Liu Hai's cannon could accomplish such a task in the whole army, so Commander Qin ordered Liu Hai to send elite gunners to be responsible for destroying the enemy who was destroying the tunnel! Liu Hai, who received the task, felt that he could complete such a task, because the No. 6 position was in his own hands, and he could send a few guns to the front position to cover the mouth of the tunnel, in addition to the fact that the US army had lost more than half of the battalion after the last battle, it had temporarily stopped, so Liu Hai decided to select a few gunners to complete this task!

"Division commander, I'll just go for this kind of task, two guns are enough!" Ghost Cannon looked at bangs and said. "Two cannons are not enough!" Liu Hai glanced at the ghost cannon and said, "The most important tunnels No. 1 and No. 2 have a total of five exits and more than a dozen vents, do you think it's okay to have two cannons?" "Then five guns, according to the position of the pit mouth and vent of our tunnel, and then carry out attack cover!" Ghost Cannon said. "It's not attack cover, it's accurate point shooting, and the impact point can't be too close to the mouth of the pit and the vent, otherwise wouldn't it be a favor for the Americans?" Bangs said to the ghost cannon. "Okay, I got it!" Ghost Cannon said. "You know a!" Liu Hai scolded, "You are a regiment leader, are you doing this job?" Just call a better company commander to go! "Yes!" Ghost Cannon said.

"Anshun!" The ghost artillery returned to his position, called over a company commander and said, "I heard that your artillery level is improving rapidly!" "Thanks to the cultivation of the regimental leader!" An Shun nodded and said with a huff. This Anshun is a veteran of the ghost artillery regiment, and he was mixed with the ghost artillery during the Anti-Japanese War, so he is very familiar with the ghost artillery! "I'll give you a mission!" The ghost cannon called Anshun over and said, "Bring five cannons and place them in these places, whether it is the Americans or the South Korean army, as long as they dare to destroy our tunnels, you will kill me with one shot, is there a problem?" "Nope!" Anshun replied immediately. Anshun knew that the regiment commander said that if he could fight, he could fight. "Remember! The impact point can't be too close to the mouth of the pit and the vent, otherwise it will do the Americans a favor, understand? Ghost Cannon explained. Be! Anshun said.

"Battalion commander, I thought of another good idea!" A platoon commander of the South Korean Army said to his battalion commander. "What's the best way to do it?" The battalion commander of the South Korean Army asked. "Didn't we already find one of their vents? We can pour gasoline down and ignite it, and I think even if we can't burn them, the combustion of gasoline will use up the air in the tunnel, and then they will either be burned to death, or they will have to suffocate to death! Said the platoon commander of the South Korean Army. Well, this method seems to give it a try! I'll leave it to you! The battalion commander of the South Korean Army patted him on the shoulder and said.

This platoon commander took five men, took five barrels of gasoline, and ran along the road in the position to the location where the ventilation holes of the volunteers they found were located. At this time, Anshun had already rushed to the location of the ghost cannon with his five guns and gunners. Anshun's location is still some distance from the mouth of the tunnel, but it is in a straight line with the mouth of the tunnel, which means that Anshun can shoot directly at the mouth of the tunnel. As soon as the artillery was fixed, the lookout spotted that several South Korean soldiers had come up from the opposite position, carrying what seemed to be gasoline drums!

"Company commander, five South Korean troops are approaching the tunnel, the goal is not clear, and the purpose is not clear!" The lookout reported what he saw to Anshun. "What do you care about them? Just kill it! Anshun picked up the binoculars and looked at the other side, and also found those South Korean troops, so he adjusted the cannon to prepare for shooting, which can be regarded as a test artillery! Anshun's artillery technology is the ghost cannon*, although it does not have the level of a hundred shots in the visual range of the ghost cannon, but at the current distance, there is still no problem. After debugging, Anshun found his own impact point, then loaded the shell, and when the South Korean soldiers ran over, they pulled the fire rope violently, and a shell rushed directly out of the muzzle and landed accurately on the impact point. And several South Korean troops who were carrying gasoline barrels in their hands and were about to set fire were bombed in an instant!

After the shell exploded, the scorching shrapnel directly tore through the gasoline barrel, and the gasoline inside flowed out, and then it burned! Although the two South Korean troops who fell to the ground were not killed by the shells, they were stunned by the shells, and when the gasoline flowed to them, the two South Korean troops were awakened by the severe pain of burning, but the fire had already spread to them, and although the two South Korean troops were desperately rolling and rolling, they were powerless and could only be engulfed in flames! The South Korean troops in the distance watched their subordinates being burned alive, and although their hearts ached, they could not do anything. However, the battalion commander did not find out that the shell was specifically aimed at those people, but only thought that a stray bullet had hit them.

"Bastard!" The battalion commander of the South Korean Army scolded angrily when he saw that his soldiers were burned, so he sent another platoon to run towards the mouth of the exposed tunnel with weapons such as *, gasoline, and *. The tunnel entrance of the Volunteer Army was not only hidden, but also had the role of defense and attack, but because of the continuous destruction of the US and South Korean troops, the original structure has been destroyed, so that the South Korean Army and the US Army continue to attack. These U.S. and South Korean troops will also use machine guns and * to cover when attacking, and the tunnel troops can only defend passively!

"It's out again! Gun Position 2 is ready to attack the enemy who has drilled out! Anshun said with a walkie-talkie to the second gun position. We've spotted the enemy and we're ready to attack! The gunner of the second gun replied. You fight first, if there is a leak, the No. 3 cannon will fill the leak! Anshun said in the walkie-talkie. Gun No. 2 understands, gun No. 3 understands! "Two gun emplacements came from the walkie-talkie." Boom! "The No. 2 artillery shot was fired, and one shell accurately hit the attack route of the South Korean platoon, and three South Korean troops were blown into the sky! One of the South Korean soldiers who was blown away was still holding * in his hand, and this South Korean soldier's * was blown into the middle of the South Korean army behind by the air wave, and there was a martyrdom! * After the explosion, it ignited the gasoline barrels in the hands of several other South Korean soldiers, and soon the explosion and combustion engulfed the South Korean platoon!

"Bastard!" The commander of the South Korean battalion saw that one of his platoons was reimbursed by an artillery shell, and his angry face changed color, but at this time, the South Korean army said that he did not believe that this was another stray bullet, and this must be the artillery specially used by the other side to cover the mouth of the tunnel!

"Sir, we must get rid of that cannon, or we won't be able to effectively destroy the tunnel!" The commander of the South Korean military battalion found the commander of the US military and said. "Don't worry, Park, it's just a stray bullet that doesn't know where to fly, you don't have to pay attention to them, concentrate on destroying the Chinese's tunnel!" The commander of the American Army said. "It's not a stray bullet, sir, have you ever seen a shell fall and kill a platoon with the same purpose twice?" said the battalion commander of the South Korean Army. "Don't be cowardly, we give you first-class security and military salary, even if you die, you also want to blow up the Chinese's tunnel and then die, understand?" The American Legion Commander said impatiently.
