The fighting in Sasiri expanded from the suburbs to the city. The secret society armed forces took full advantage of the firepower of the tank guns and well-trained tactics to enter the offensive stage from the defensive warfare in the urban area. The mercenary and militia units started from the initial assault, and switched from active attack to defensive operations. Under the constant threat of enemy forces, they must consolidate the southern part of the city.

Relying on powerful artillery cover and the support of armored vehicles, the Red Baron commanded his troops to organize a fierce counterattack. With a counterattack to the south of Sasrimi, another fierce exchange of fire began.

General Hassan’s forces came to the flank of the mercenary force to prevent the enemy from counterattacking. General Hassan's troops also bombed some of the original fortifications.

The secret society armed forces violently bombarded the mercenaries' positions. The defensive fortifications were left undamaged, and some civilian buildings were also bombed and collapsed.

During the fighting, one helicopter of the mercenaries was destroyed, the other was wounded and fled staggeringly.

The secret society militants concentrated their artillery fire on the mercenaries, and then stepped forward, using the cover of machine gun fire, the infantry surged up like a swarm. The defenders of the Trident Company immediately confronted them with machine guns and grenades. But the intensive artillery fire suppressed their defenders in the fortifications. Seven or eight secret agency-armed armored vehicles were laid out, ready to assault across the board.

At this time, the mercenaries have suffered a lot of casualties. Faced with the tide of the enemy forces, they launched another counterattack. The two mercenary team leaders who organized the defense, one was killed and the other seriously injured. The troops that lost their command were immediately destroyed by the armed forces of the secret agency.

The secret society armed forces occupy several important positions. General Hassan led his troops to come for reinforcements. Although everyone is courageous, it is difficult to achieve results in a short period of time due to the weak force and heavy casualties.

In the midst of a crisis, the members of Group B of the O2 team, with a large number of armed mercenaries, were ordered to stop them.

Their unit is equivalent to Lin Rui's teaching team, and its military quality is better than ordinary mercenaries. They are trained by Lincoln and their equipment is not bad. After receiving the order, he immediately moved forward through the artillery blockade and exchanged fire with the enemy. In the face of the enemy's intensive artillery fire, shells and bullets fired here at the same time. Mud splashed and smoke filled with gunpowder. In the raging shrapnel fire, the mercenaries fought back at the enemy.

There are sacrifices at all times. A mercenary leader of the fire team fell, and a company commander of Hassan's was also killed by the enemy's blocking gunner, with the bullet penetrating the helmet.

The reconnaissance team, which had already penetrated into the enemy army, sent soldiers to the front for reconnaissance, but it hadn't come back for a long time. The gunfire gradually faded. Lin Rui's mercenary unit was on the right and Hassan's militia unit was on the left, changing and advancing alternately. About 500 meters ahead, the secret society militants who had arrived were hiding in sandbags and ruins of buildings on the roadside.

Neither side dared to expose the target. The sun slanted westward, and the day's battle was about to end. Beside the ruins on one side, some mercenaries covered in blood and dust lay on the ground, and some were still groaning.

"Which unit are you from?" a mercenary asked.

"Sixth Company, General Hassan's men." A soldier replied feebly, "We have only a few people left, and we can't withdraw." The fighting between the neighboring troops was still very fierce. Creeping to a dead end of shelling, the head of the reconnaissance unit Lincoln led his soldiers to spread out beside a building. Using nearby buildings to cover and lurking, they have to pick up two scouts.

Soon the two scouts bent down all the way and ran over in a serpentine shape. As soon as they were near them, a string of bullets flew, and the scout was shot in the right leg. He rolled over and crawled into the sheltered area. The other mercenaries immediately tore open the first aid kit, stuffed hemostatic medicine into the wound, and bandaged the wound layer by layer.

This scout is a veteran and experienced. He gritted his teeth and said to Lincoln: "The troops in front, only... 4 people survived. The casualties of the other two platoons... are also large... no... no more... assault. It's...and...don't...retreat...the enemy...look...we...clear...retreat...danger...we don't... move, hold on..." He passed out after speaking.

As night fell, hunger and pain hit everyone. It wasn't until 9 o'clock that the gunfire subsided. But the soldiers still can't rest. They have to dig fortifications and prepare to stand by all night. Although the possibility of secret agency militants launching a surprise attack at night is not high, they still have to prepare for tomorrow's battle.

At dawn the next day, the secret agency armed forces discovered this temporary position. Multiple companies attacked here at once, causing more and more casualties. In General Hassan's sixth company, a platoon leader had already taken over as the company commander, but before long, he was shot again in the left shoulder and passed out. The entire company has become under the command of the soldier squad leader, and there are only more than twenty people left in the company.

At this time, the troops of the People's Front of Western Sahara had pushed the front to within the ring road in the city. Although the militia forces in the northwest were attacked by the secret agency, they were not the main attack and could retreat flexibly, so they can still entangle with the enemy and have not been completely repelled. The main force of the secret society has directly threatened the mercenary troops in the south. For this reason, Lin Rui ordered the suspension of the attack on the enemy. Stand firmly on the spot, and transfer two battalions of General Hassan and General Quinn to siege.

After 2 days of **** battle, part of the Red Devil army surrounded a small area east of the south of the city. In the afternoon, General Quinn launched a fierce attack, and the reinforcements of the secret society retreated to the vicinity of Sasrimi Station at night.

The mercenary led by Lin Rui was a commando team. He led the troops to an intersection about 400 meters away from the enemy's control zone and immediately dug a fortification bunker nearby. He knew that this was the only way for the enemy.

Sure enough, the enemy rushed to this position. Lin Rui concentrated more than 10 armed vehicles and set up machine guns to blast the enemy violently on both sides of the intersection. At the beginning of the battle. They used artillery and infantry in concert to fight against the defenders. Before launching an attack, 10 to 20 minutes of artillery bombardment must be carried out. In this way, most of the fortifications on the front line were destroyed, and the subsequent charge and counter charge became more intense.

Lin Rui's mercenary troops stood firm at the main intersection in the south of the city, repelling the enemy's many attacks, but they also paid a great price, with considerable casualties. The brutal war caused Lin Rui and the actuary Jiang An to find ways to reduce casualties. Later, according to the recommendation of the actuary, a two-line configuration was adopted, and the second line was about 300 meters away from the first line.

A small number of mercenaries were left on the first line for command and observation, and the rest were on standby at the second line. After hearing the observer's signal, they entered the first line to fight, minimizing casualties.
