A high-pitched siren sounded throughout the area.
Soldiers on both sides of the Euphrates River could hear it clearly.
The Union soldiers didn't know what had happened, so they all immediately woke up from their slumber and entered combat mode.
On the side of country Y.
As soon as the sirens were heard, it was clear that the covert operation should have been exposed.
According to the scheduled plan, all excavation operations were immediately accelerated to break through the last layer of barriers.
flutter! flutter! flutter!
Bang! Bang! Bang!
clatter! clatter! clatter!
boom! boom! boom!
The elite soldiers of country Y started a fierce battle with the patrol soldiers in the passage.
One side is desperately trying to attack, the other is desperately trying to stop it, and the two sides are fighting at all costs.
6 minutes later, the FA League side.
A loud loudspeaker emitted an artificial voice and began to issue blockade orders.
"The enemy has discovered the underground tunnel, and the command headquarters ordered all guards to activate emergency plans immediately."
"Order, all security forces along the river to immediately enter combat positions to stop the invading enemies."
"Order, the reserve troops quickly seize the commanding heights and reinforce the posts along the river."
"Order, all tanks, mountain artillery, and rockets are ready and ready for attack orders at any time."
"Order, all soldiers should stick to their posts and guard against any enemy. Any enemy who loses their position will be punished by military law."
"The order is repeated again..."
Both sides of the Bura River.
Sirens and horns sounded continuously, the situation became tense instantly, and gunfire began to exchange fire intensively.
The passage where the alliance team leader Aka was located, because the patrol soldiers withdrew in time, and after the elevator was powered off, it was like an iron wall blocking the advance of the elite soldiers from the Y country.
In the other 19 hidden passages, there were varying degrees of fighting due to the reaction time.
The raiding force came well prepared and had a numerical advantage, and quickly won most of the tunnel contact battles.
The guard at the entrance of the underground passage heard the siren and hesitated because the situation was unclear.
Immediately, through the loudspeaker command, he knew that the secret operation had been exposed, and he no longer cared about the life and death of the soldiers patrolling the underground passage. He ruthlessly cut off the power and turned on the switch, killing the enemy's attempt to break out of the ground.
Things always change.
Three of the entrance guards were closely related to the underground passage patrol team and wanted to rescue their comrades, so they lost their last chance and made fatal mistakes.
At the exit of an elevator, a dozen guards pointed their guns at the elevator door. When they saw the soldiers coming out, wearing the same clothes as them, but with very unfamiliar faces, they were momentarily stunned.
2 seconds of hesitation.
The silenced firearms of the dozen assault elites in the elevator breathed fire.
flutter! flutter! flutter!
Boom! Boom! Boom!
The ruthless armor-piercing bullets first connected like lines, penetrated the protection of the body armor, entered the opponent's body, and gave off a metallic texture like exploding beans.
In order for this raid to be successful, Country Y used almost all of the nearly a hundred armor-piercing guns allocated in the first wave of attacks.
clatter! clatter! clatter!
Boom! Boom! Boom!
The alliance guards and delayed counterattacks were ultimately unable to stop the opponent.
At each exit, the alliance guards were only equipped with two armor-piercing guns. Ordinary bullets would not be effective unless they hit the vital points. Their movements were a beat too slow, and they could not block the opponent's crazy bursts of fire.
Within a minute, all the guards were knocked down.
The raiders who succeeded in the attack were very skilled in cooperating and quickly secured the high-energy power supply room and the entrance elevator, allowing the following soldiers to rush out of the ground.
The encounters in the other two places were almost the same, and they became a new strategic breakthrough for Country Y.
According to the plan prepared in advance by Country Y's frontline headquarters, the current progress of the battle can be regarded as a middle strategy and in line with the expected results of the plan.
It can be said to be an initial success.
After learning that there were three entrances in hand, the frontline commander of Country Y was overjoyed and immediately ordered the implementation of the second phase of the plan.
Other elite warriors carried the necessary equipment according to the order, moved to three underground passages, attacked or drilled out from the other side, and entered the town to fight as quickly as possible.
The alliance lieutenant colonel who received the report from squad leader Aka quickly realized that the situation was critical and quickly issued a loudspeaker order to notify all riverside troops in the area to prepare for battle.
Considering the serious impact of abandoning his subordinates, he did not openly order the guarding soldiers to immediately abandon the underground passage patrol, but only asked his subordinates to implement the emergency plan.
The meaning has been made very clear, it depends on the subordinates' emergency response.
However, a bad situation still occurred.
The Alliance Lieutenant Colonel heard reports that there were fierce exchanges of fire at three entrances, and understood that the situation was truly critical.
"Order, the reserve troops must retake the entrance at all costs, and the Persian cats must not be allowed in, quickly."
"Aka, you have made great achievements. I will promote you to captain and lead the second brigade to the scene. We must recapture three places."

The searing pain caused them to howl miserably and keep rolling and twisting.
"Quick, high-pressure water-based fire extinguisher."
A sneak attack soldier pushed a water tank out of the power room and sprayed violently at his burning companions, temporarily extinguishing the open flames on them.
Fortunately, it didn't last long, and with the protection of the body armor, only the connection part was seriously injured.
Of the dozen or so people, only a few were still able to fight, while the rest were seriously injured on the ground.
At two of the three entrances to the passage, the power lines were burned out. The soldiers below were unable to come up. The surviving guards rushed to repair the wires.
"Quickly remove the guard bunkers in the upper passage."
On the side of country Y.
The raiding force found that the elevator transport was too slow and would be even slower if interfered by the opponent. They had no choice but to organize their forces at any cost and launch a fierce attack on the nearby bunker at the entrance to the upper passage.
After suffering many casualties, they finally succeeded in controlling two of the places.
The upper-level tunnel assault troops had already fought their way out of the underground, rushed to the alloy gate leading to the ground, and began cutting the heavy gate.
Alliance side.
After Captain Aka arranged the blocking mission, he rushed to the top of a building.
Through the telescope, I found that the guard bunkers at the entrance to two of the passages had lost their firepower, and I understood that the enemy had probably captured two places.
After determining the coordinates, he immediately ran downstairs, reported the situation to the rear tank commander in the nearest wired telephone room, and requested artillery coverage.
In fact, in these two places, the Alliance guards in the bunkers had already pulled the tunnel's self-destruct switch before they died.
As soon as the 120-second countdown expired, the raiding troops who were cutting in two places immediately saw the alloy gate. The walls on both sides exploded violently, and the rolling sand and stones immediately blocked the passage.
The cutting personnel of Country Y were immediately buried in the soil.
Country YNot far behind the charging soldiers, the cover on the top wall of the passage leading to the bottom of the river was not blown up at the same time.
Previously, State Y's engineers had cut off the control lines and released electromagnetic interference, blocking the detonating device above their heads in time.
"According to groups, dig quickly and be sure to clear it within 2 hours."
The team leader from country Y behind saw that the cover plate had not exploded, so he made a tentative decision and immediately issued an excavation order.
If you want to clear a blocked channel of more than ten meters within 2 hours, you must organize it rationally and go all out to complete it.
At the same time, the wires were reconnected at the entrances of the three passages.
The elevator continued to run, and the raiding troops from Country Y spewed out intermittently to reinforce the defense line that was about to collapse.
boom! boom! boom!
Immediately afterwards, tank fire from the Alliance side began.
The penetrating artillery shells bombarded the upper and lower entrances of the three passages in turn, causing heavy damage to the Y country's raiding force who had no time to escape.
Unfortunately, the elevator room and power room built by the alliance were originally designed to defend against the opponent's heavy tank fire. Although there was a hail of bullets outside, the Y country soldiers hiding inside were unharmed.
I have to say, this is a big irony.
Captain Aka, who observed this situation from above, was on the verge of crying.
Aka is responsible for patrolling the passage every day and has a deep understanding of the strength of this place.
He knew that there was a very narrow passage between the elevator exit and the power room, and no matter how fierce the artillery fire was, it could not stop the other party from continuing to transport.
The high-energy reserve power supply in the power room can provide at least 2 hours of power.
Once the opponent is allowed deep into the town, the battle situation will fundamentally change.
What he could think of was that the rear headquarters and the lieutenant colonel who received the situation report were also informed.
"Attention all troops, we must defend the second line of defense and we must not lose it!"
"Oil bombs are fired intermittently at the three entrances to the bottom passage to delay the opponent's troop recruitment."
"Brothers from the alliance, the nearby reinforcements will arrive within an hour, and the large armored forces at the rear will arrive within two hours. The time has come for meritorious service. If we hold on, we will win!"
The lieutenant colonel was in the underground command room, giving orders to the microphone connected to the external loudspeaker.
After boosting morale, the remaining reserve troops were immediately moved forward to build a third line of defense.
He wanted to guard the main road leading to the big city behind and prevent the worst outcome.
At this time, in order to quickly convey the order information, he no longer cared about exposing the reinforcement action plan.
Conveying confidence and holding on to the position is the most important task at the moment.
Anyway, it doesn't matter if the other party listens. The aerial reconnaissance drone will find specific signs sooner or later. Whether it is exposed or not has no bearing on the outcome.
