Lin Rui was at the observation station and continued to take the telescope to observe coldly. At this time, the Orumi Federal Army on the opposite side had already appeared in his field of vision. Composed of a group of infantry, loose formation. Their BT series light armored vehicles are unable to pass due to terrain restrictions.

Shen Qian counted carefully. The reconnaissance unit was in front, followed by the densely packed Orumi Federation infantry. Their steel and boots indicated that this was the main force of the Orumi Federation.

Before many Orumi soldiers were armed with old-fashioned AK47 rifles, but many soldiers in this unit were equipped with M14. This shows that this is one of the Orumi Federal Forces that has received US military training and is equipped with NATO-standard weapons.

A large number of infantrymen moved forward unsuspectingly, because according to the information they received, the enemy was still located in a distant residential area.

"It's almost there. Boss, what shall we do, do we follow the plan?" Sausage asked softly.

"Of course, just follow the plan!" Lin Rui put down the telescope.

Sausage took the radio: "All troops are in place and act according to plan!"

"Yes, sir!" A neat, hoarse answer came from the radio.

"Huh...what a bunch of idiots, don't they even use armored vehicles?" Eric, who was lying on the trench and also observing the formation of the Orumi Federation forces on the opposite side, mocked.

"In this way, the infantry without artillery preparation and armored cover is concentrating through a large uncovered area. It is a suicide! If the infantry and armored vehicles charge together, maybe we have to be afraid, but now... they are too anxious." Ma also said with emotion.

No wonder they are so emotional, because they have everything ready.

Relying on the deep and strong position of the school building, the Orumi Federal Forces did not have artillery that could seriously threaten them.

Although those lines of defense were laid out hastily. But relying on the strong building of reinforced concrete structure. Without heavy fire coverage, it is impossible to cause too much physical damage to the soldiers inside.

There is enhanced firepower on the periphery of the teaching building's defense line, and there is a civil structure bunker over a dozen meters away. The machine guns and grenades inside are enough for these infantrymen to be in a hurry.

In addition to these there are several hidden large-caliber anti-aircraft machine guns. Anti-aircraft anti-aircraft machine guns are generally called high-level dual-purpose machine guns. It can be known from the name that it can be used as an anti-aircraft weapon or as a suppression weapon for flat-fire on ground targets, but the range is different.

If the effective distance can reach 2000 meters when shooting in the air, the effective distance will be smaller when shooting in the flat. This is because when shooting in the air, the bullet flies high, and the higher the altitude, the thinner the air, so the air encountered The drag will become smaller, thereby extending the flight distance.

However, the flying height of the bullet does not change when it is fired horizontally, and the air resistance encountered will not gradually decrease, so that the flying distance of the bullet will not be as long as when it is shot in the air.

Although the shooting distance is reduced, the caliber of anti-aircraft machine guns is large, including 12.7 mm and 14.5 mm. The bullet power is much larger than ordinary pistols or rifles. More importantly, anti-aircraft machine guns generally use multiple combinations, including double or even quadruple. United.

For example, the Type 58 14.5mm twin anti-aircraft machine gun in the 1960s has an effective range of 1000 meters. Once this weapon is fired, it will spit out a rapid flame. Anyone exposed within its range will be hit. A flat shot will have a very large damage effect, and the chance of survival is very small.

If the hit position is in the center of the body, the whole body will be scattered. Even if it hits an arm or leg, the huge penetrating energy of the projectile is enough to kill a person.

This ZPU-2 double-mounted 14.5mm high-level dual-purpose machine gun not only has a larger caliber than the M2, but also has a very fierce rate of fire. The theoretical rate of fire is about 1200 rounds per minute, and the effective range is 1,000 meters in plain shooting.

This is beyond the range of the Federal Army of Olumi. These things are set to fire flat. The horrible firepower is enough to send the Federal Army soldiers of Olumi into the **** without leaving any scum. .

To the rear of the teaching building are the positions of 81mm and 120mm mortars. These mortars fire projectiles that can fly in a parabola. Their role is to strike the enemy's rear targets.

"Boom" Most of the Orumi Federal Forces only now felt the sound of gunfire, muffled. "Shoo..." There was a harsh sound in the air, and the experienced soldiers leaned down and hugged their heads, lying down as much as possible, with their mouths open. That is to reduce the damage to his tympanic membrane caused by the huge sound waves during the shelling.

"Boom..." Numerous pieces of dirt and dust rose up in the open space in front, and tree **** and stone fragments flew everywhere.

After the shelling, the communication channel was followed by extremely chaotic, but extremely orderly, passwords. After the voice of "Dang Cang Dang Cang...", various dust-covered helmets emerged from the trenches. "Fire!"

"Boom..." The multiple hidden firepower points in front of the position opened fire, and orange-red, terrifying fire lights continued to flash in turn. Started a new round of roar.

The flat and straight trajectory of the anti-aircraft machine gun was clearly visible in the air. When I looked up, the sky above my head was red. The grand feast of the massacre has begun...

"Machine gun ready!" the head of the mercenary commando in the trenches shouted, "fire!"

"Suddenly..." The machine gun fire started a stormy shooting, and violent bullets poured down like a heavy rain. "Ah..." Dozens of soldiers from the Orumi Federal Army on the opposite side immediately fell down.

Lin Rui saw through the telescope, the wounded soldiers who fell on the ground were clutching their hands and wailing in pain. The rumbling cannons couldn't hide their heart-piercing howls.

The soldiers of the Orumi Federation marched forward with intensive artillery fire and bullets. On the way forward, people continued to fall, but no one stopped or retreated. Because the commander in the rear strictly ordered the attack, he must not engage the enemy for a long time in this open area.

The mercenary mortars continued to fire, and the Union soldiers of Orumi were blown to the ground during the charge, and people were constantly wailing to the ground and could never stand up again.

At the time when the firepower of the blocking team reached its maximum, almost all weapons began to shoot frantically. Several automatic grenade launchers, fired grenades, dashed white smoke into the middle of the Orumi soldiers, and even a few A soldier was blown up by this unprecedented intensive bombardment.

The stump has a broken arm, **** gunpowder. In an instant, the entire abandoned campus was stained with the red and black colors of war.
