Three or four hours passed, with numerous casualties among the soldiers and many losses in tanks, but there was no progress in the offensive, and there was no hope of a breakthrough, so the troops could only temporarily retreat and urgently request tactical guidance.

Texas, the former enemy headquarters of the National Army.

Jiang Haoran trembled slightly with the telegram in his hand, and muttered miserably in his mouth: "Dragon teeth, it's dragon teeth, they actually built a dragon tooth defense line?" ”

"Dragon's teeth? What is a dragon's tooth, is it powerful? Lin Long asked anxiously.

The so-called "dragon's teeth" are actually anti-tank cones, a triangular pyramid cast from concrete, similar to a pyramid, about half a meter high.

During the war years, when tanks were king, anti-tank weapons were also emerging. In order to deal with the ferocious steel armor and iron flow on land, countries have also tried their best to create not only a lot of high-tech anti-tank weapons, but also many simple and low-cost anti-tank weapons.

The most famous are the Czech "Czech Hedgehog" and the German "Dragon's Tooth", the former is an anti-tank obstacle made of angle iron welded with L- or H-shaped steel crossed into a higher cost.

The "dragon's tooth" invented by the German army is a triangular pyramid made of concrete, which is arranged in the combat area, resembling a pyramid, about half a meter high, the structure is very simple, and the cost is extremely low, and because of this, it was used in a large area of ground warfare during World War II, and it was a nightmare for tanks and armored vehicles.

The Dragon's Tooth anti-tank cone has three planes, and when the tank wants to climb over the anti-tank stack by climbing the slope, it will be stuck on it because both tracks are on the triangular cone without a point of focus, as if it was jacked up by a jack, even if the tank can find the point of focus to accelerate, it is impossible to get rid of the support of the anti-tank cone.

Because driven by the tank, every time the anti-tank cone rolls, it will turn over an edge, then the tank will still be stuck after all, and if it is not blasted, the tank will not be able to move at all.

The first time the Germans used the dragon's tooth was in the Normandy landing, the beach was densely packed with triangular pyramids, which brought great casualties to the Allies, so the Germans called it "dragon's tooth", meaning an impregnable defensive line.

In fact, in modern warfare, this weapon has long been obsolete and withdrawn from the stage of history, because now the emphasis is on precision strikes, and such large-scale war scenes in World War II are no longer easy to see, so there is no place for anti-tank cones.

The reason why the anti-tank cone was able to become an important weapon in the later stage of World War II was because in this special era, the information was relatively backward, and the wars between the two countries were mostly large-scale military confrontations, and it was impossible to accurately judge the enemy's military posture during the war, so most of the military operations were blind advances with high consumption.

Most of the wars are carried out by ground armored forces, and the war of attrition between countries is high-attrition, so this gives the anti-tank cone the opportunity to show its skills, although it cannot directly cause damage to the tank. However, it can cause a lot of trouble to the enemy, so it is more practical than other anti-tank weapons, and it has become the best weapon to restrain tanks.

It's a pity that Jiang Haoran's brain is stored with some high-tech weapons, and there is no record of these "native products" at all, and his cognition of dragon teeth is completely based on his love of military affairs in his previous life.

After Jiang Haoran's explanation, everyone has a basic understanding of the dragon's teeth, but without exception, they all choose to be silent, Jiang Haoran can't solve the problem, who still has the ability.

After a long time, Jiang Haoran finally broke the silence and said in a deep voice: "Order Jinghai and Dingxing to suspend the attack, and the troops retreat to a safe area." Xu Biao was ordered to send the heavy artillery brigade to Ba County. ”

Bai Chongxi was dumbfounded, and there was no reaction for a long time, the heavy artillery brigade was a strategic-level unit, and at this time, Jiang Haoran made it clear that this was going to be attacked.

"It's not...... Ziqian, now we have learned that the enemy's second line of defense is not at all a temporary fortification as we know it, but a permanent fortification, the defense line is full of hidden forts, the artillery fire has been specially treated, we can't blow them up, but they blow us up just right, and there are anti-tank cones in front to hinder the advance of the tank troops, so how many soldiers do you have to fill in if you forcibly attack? ”

At this point, it is already basically certain that in the intelligence war, the national army is completely defeated, and it is very likely that the enemy's first and second lines of defense were built at the same time, and they have achieved absolute invisibility, and the intelligence department of the national army knows nothing about this.

Of course, the key problem is that the intelligence department of the national army has undergone an important reorganization at this stage, and the Central Security Bureau has replaced the Central Unified Bureau, and it is needless to say that the turbulent internal wars and internal contradictions during this period have also led to a period of confusion and inaction in the intelligence system, which can be regarded as a reason.

Jiang Haoran hesitated for a few seconds and said, "Do you have a better way?" ”

Bai Chongxi immediately got stuck, yes, if there is any other way, who would choose this bloody tactic.

"Napalm bombs? Can we use napalm•bombs? Leng Rushuang on the side suddenly said: "Choose a remote area far away from the city, and blow up a gap and wedge it in." ”

"Hey, this suggestion of Division Commander Leng is good, with the power of solidification, there is no problem in burning these anti-tank cones into dry powder, as long as there is a hole in the tank can drive in, open the way with the composite armor of the battle leopard, and cover the infantry to pour in, it will definitely be able to tear through the enemy's defense line." Bai Chongxi excitedly agreed.

Jiang Haoran rolled his eyes and looked at the two of them, with a look of disdain, and said coldly: "You think the enemy is all pigs, it's time for the enemy to let your plane fly above their heads and drop bombs?" In addition, if napalm is dropped, the fire will not be extinguished for a short time, and the enemy will be able to block the opening before the fire is extinguished. In addition, I can assure you that the enemy's anti-aircraft fire will be built up to be unprecedentedly strong, and as soon as we have the intention of air strikes, we will immediately usher in a brutal air battle. ”

The two looked at each other, and a trace of excitement slowly faded on their faces, Jiang Haoran was right, since the enemy was so well prepared, these factors must have been taken into account.

From all things point of view, this tank warfare expert from Germany is not a straw bag, at least this dragon's tooth defense line is very clever, simple and efficient.

At the moment, I am afraid that there is really no better way than to attack, but tomorrow this casualty...... Alas!

The people in the headquarters felt numb in their scalps just thinking about it, and their hearts were cold.
