After Wei San and the others left, they went directly to the Iron Triangle area in Pi Dingjun's mouth, which is only twenty kilometers away from Seoul and belongs to the second gate of Seoul, as long as they pass here, they will not be far from occupying Seoul.

The Iron Triangle is so called because it is a pass made up of three hills that rely on each other to guard the perimeter of Seoul.

In the center of the three hills, there are the enemy's artillery units, two artillery regiments, and even more powerfully, here is the commander of the US 8th Army, Lieutenant General Walton Walker (the original history of this lieutenant general had died in a car accident in December 1950, and he was considered the most deadly lieutenant general)!

Speaking of the U.S. 8th Army, it can be said that it is the dominant force of the U.S. military on the Korean battlefield, the 8th Army was originally a garrison after the occupation of Japan, and after the start of the Korean War, this group army landed on the Korean Peninsula.

In addition to the main force, the establishment of the 8th Collective Army can be described as diverse, in addition to the infantry divisions, there are also units like the 1st Cavalry Division, but the 1st Cavalry Division was unlucky and was beaten into a cripple, and both men and horses were lame.

There are also such units as heavy combat brigades, fire brigades, combat aviation brigades, support brigades, anti-aircraft artillery brigades, medical brigades, service regiments, military intelligence brigades, and even some units of South Korea are incorporated into the sequence of the 8th Army.

Therefore, the firepower and strength of the 8th Army are very amazing, and naturally, the arrogance is also very amazing.

If you are not arrogant, you can only call a ghost, and an artillery regiment of the US army has five times the firepower of the volunteer army!

Of course, this is not compared with the 38th Army at the landlord level.

The artillery regiment of the US army includes 4 howitzer battalions, 1 headquarters company and 1 artillery service company, each battalion is equipped with 12 155mm howitzers and 36 105mm howitzers.

In addition to heavy artillery, blows from the sky are naturally indispensable, plus the terrain here is extremely advantageous, as long as they gain a firm foothold on the mountain, they don't even need the troops on the hill to counterattack, just use their heavy artillery to repel any form of attack!

The Yankees are not bad for money, and artillery is always calculated by the hour, such as MacArthur's unit of counting: another 10,000 tons of shells!

Wei San asked Zhou Weiguo for 500 shells, which can be regarded as draining the 38th Army, and the gap between the two sides can only be said to be a world apart.

According to what Commander Pi told Wei San, this triangle area is very important, for the sake of later arrangements, it must be fought down here, and there are still 21 hours left before the time given by Mr. Peng, the time is very tight, and the task is very heavy!

Pi Dingjun's task to Wei San is to destroy the enemy's logistics supply, and not let the enemy send a single shell into the triangle area, this is a mission behind enemy lines, Pi Ding will not give Stinger any support and help, so the special combat team can only find a way to complete the task by themselves!

In fact, to put it simply, it is to let the special combat team go to the rear of the triangle area to destroy the enemy's transportation lines!

Just like the enemy's special bombing of the volunteer railway, the special combat team went to sabotage the US military's highways, and after the US military's trucks were paralyzed on the road, the US army's artillery fire was cut off.

Time was very urgent, Wei San and they made some preparations, and they went to the front line and found the 24th Division of the 73rd Army.

The reason why he came here was because Wei San wanted to find someone to lead the way, and to see if there was anything he could do, the destruction of the road was not in a hurry, and the time given by Pi Dingjun was eighteen hours, which was enough for the special combat team to do a lot of things.

After walking around the position, showing the note given by Pidingjun and asking about the surroundings, the special combat team, led by a scout, went around the triangle and went behind the enemy's back.

As for the destruction of the enemy's transport lines, the methods that the volunteer army can use are relatively monotonous, and there is no other better way except to bury mines and dig pits.

But Wei San also brought one more thing, and that was the nail board!

Compared with nails, mines are heavier and bulky, and they are not easy to carry, but nails are easy to carry.

The people of the special combat team didn't expect that they would let themselves do civil engineering operations, and they thought that they could kill people on the front line.

"It's boring, let's send a mission like this on a trip!" Hiding in a dense forest, Chu Jian complained.

"It's better than staying on the top of the mountain in a daze, and if the situation allows, we can still ambush us." Wei San pulled up a freshly grown grass and bit it to his mouth.

"Cold shots!? This is good, I can just practice marksmanship, captain, you can teach me to play sniper rifles! Chu Jian sat down against Wei San.

"Can you hold your breath?" Wei San picked up a stick of grass again.

"Of course!" Chu Jianxing said angrily.

"In that case, you take this grass and stare at it, keep it still, and see if you can hold on for half an hour!"

Chu Jian took the grass, pinched it with two fingers, and put it in front of the bridge of his nose: "Is this practicing cross-eyed?" ”

Waizo: "You can choose to look with one eye." ”

Chu Jian closed one eye, and the other eye stared at the grass without moving, and the surrounding team members began to become interested, wanting to see how long Chu Jian could hold on.

But everyone looked at it for a while, but they gave up earlier than Chu Jian, who would stare at a motionless person?

A group of team members leaned against the big tree with their backs, waiting for the sunset, according to what Wei San said, they could only act when it was dark, otherwise they would not be discovered by the enemy immediately when they went up the kilometer in broad daylight?

Chu Jian's face was expressionless from the beginning, and gradually frowned, ten minutes, Chu Jian felt that he was so stupid now, always thinking about throwing away the grass in his hand, and gradually Chu Jian began to have various thoughts in his mind, and he couldn't keep his attention focused.

But he still gritted his teeth and persevered.

Wei San, who was recuperating with his eyes closed, lifted his eyelids and said teasingly: "Do you want to give up?" You'd better give up, you won't be able to hold out for half an hour! ”

This is the captain creating external factors for himself, and he can't be fooled!

Chu Jian thought so in his heart.

It's been fifteen minutes since he maintained his motionless posture, and Chu Jian felt like he was about to collapse, what was this? A test of endurance or a test of observation? There must have been a lot of people around laughing at themselves.

"Give up, don't do such a ridiculous thing!" Wei San is still making it more difficult for Chu Jian.

There are indeed people around who have been paying attention to Chu Jian, because some people have tried, and it is not easy to maintain such a state, and some people will automatically give up after experimenting, so they want to see how long Chu Jian can last.

Twenty minutes later, although Chu Jian didn't make any movements, he actually saw sweat on his forehead!

One person can do it without moving, but you can't do it without thinking about anything!

(If anyone is interested, they can try it themselves.) ）
