There was another burst of very rapid artillery fire. Based on the calculation of the direction and range of the artillery, Lin Rui knew that it was those vehicle-mounted mortars outside the valley. .

If it weren't for terrorists, the number of such artillery is very limited! Their positions had already collapsed across the board, and when Lin Rui experienced the shelling for the first time, he had the idea that the mouth of the valley would not be able to be held. A huge crater with a diameter of several meters. The burning hay is smoking! Looking at this huge crater with green smoke, Lin Rui couldn't help fighting a cold war!

"Retreat!" Lin Rui whispered, "We must retreat. The opponent has a master."

"What?" The tailor was taken aback.

"Several of their vehicle-mounted mortars can't get in outside the valley, but their strikes are quite close to our defense point. They almost killed me. What does this mean?" Lin Rui whispered.

"The artillery requires prior reconnaissance, calculations, and even test firing, and ballistic correction. They can find our approximate location without any personnel coming in. Is it just based on the judgment of the gunfire?" Scarface's eyes moved.

Lin Rui nodded, "Although most of the artillery fire is deviated, the general target is not much different. This shows that there are very experienced artillery in the opponent, and they are very good at this kind of vehicle mortar. And those terrorists There are very few such people. For them, the equipment of mortar is too high-end. What's more, most of the vehicles on the vehicle are of larger caliber types, and the general terrorists rarely use these." Yelena also Nodded.

"Think about it, when we were fighting in Anmore. Are some of the characteristics of the artillery unit of the secret society similar?" Lin Rui whispered.

Scarface said in astonishment, "Could it be that the secret society armed forces also collude with these terrorists?"

"It's still not certain, but this is absolutely unusual." Lin Rui whispered, "Retreat, let's retreat for a while. Their mortars are limited and they cannot use the barrage advance tactics. They can only rely on general We had a small volley of fire from the crossfire position. We had to retreat for a while and they had to relocate after they launched another ground offensive."

Barrage Xu Jin tactics, a method of impact artillery support. It is formed in one area in front of the front of the attacking army or on two areas at the same time, and as the attacking army advances, it successively extends to the depth of the enemy's defense to a dense barrage. Simply put, when the infantry is charging or advancing, the artillery extends the artillery fire in a certain order, always hitting the artillery shells hundreds of meters in front of the infantry, providing the infantry with fire cover.

But this tactic must have a certain number of artillery and a large amount of ammunition to be possible. The number of artillery and ammunition of these terrorists certainly cannot.

Therefore, their artillery fire was intermittent, relatively scattered, and lacked the most necessary reconnaissance for artillery tactics. This gave Lin Rui and others enough time to evacuate, and the range of the valley was large enough to give them enough back. Withdraw space.

As the terrorist force approached the forward position ten meters away at the mouth of the valley, Yelena detonated a pre-embedded directional mine! After the lightning flashed, the originally buried directional mines only flashed a few sets of sparks. Obviously there are only these groups of landmines left. Although directional landmines caused a moment of chaos and seriousness to the terrorists, they quickly reversed their disadvantages based on their quantitative advantages, and more and more terrorists began to enter the valley. Entrance!

The Scarface, Tailor and others on the second and third lines all returned to the light and heavy machine gun firepower point, and immediately began to cover and shoot the first line indiscriminately according to Lin Rui's previous combat plan.

And at this critical juncture, the mortar shells used by these terrorists as fire suppression have also been exhausted! After all, they are not a regular artillery unit, and the vehicle-mounted mortars originally played the role of battlefield support. It's not used to attack tough ones.

Lin Rui hastily wrapped around his waist, and when the valley position was about to be breached, he rushed to the position again! The machine gun firepower set in advance cooperated with other team members to form a downward blockade cross firepower. The sweeping of the dual-line guns destroyed them.

After a beautiful counterattack, the terrorists who abandoned the corpse base were restricted to the first line of Taniguchi! But the position on this side had just been stabilized, and terrorists lacking artillery support broke through the high **** on the side of Taniguchi. After breaking through the peak position in the middle section, the terrorists did not stay at all and immediately launched a new offensive!

The fanatical extreme terrorists, led by their officers, started shooting from the top of the mountain on the other side to suppress them.

"Damn, they rushed to the opposite hillside." The tailor who discovered this situation immediately fell to the ground, moved the machine gun, and bursts of bullets shot at the terrorists who lined up in a group of shocks!

When the blood mist floated from the body of the terrorist in the front row, the other armed terrorists still waved the AK47 and the bazooka in their hands frantically without notice. Rows after rows of militants were shot and fell to the ground, but this did not affect the fanaticism of these people! Because they found that their opponents were already in front of them, and there were not many people! And now all they have to do is to work harder, it's that simple!

However, the well-equipped O2 team members, who are determined to tactically outperform them, have made the dreams and efforts of these terrorists come to nothing!

Scarface stuck his head from behind the bunker, carrying an RPG rocket launcher on his shoulders, and shot a rocket in a crowded place. For a while, the flames blazed into the sky, and the explosion of 40mm rockets formed the flames. The terrorists who were shooting were swallowed up in the flash of explosion! Broken clothes, broken limbs and broken arms also fell along with the earth and stones falling from the sky.

The terrorists came to reinforce them again, probably from another camp, which boosted their morale. They lined up in dense formations to repeatedly hit the highlands of the Black Camel Mountain.

Through the telescope, Lin Rui quickly discovered that the opponent's flank attacking the main peak had no cover. Lin Rui felt a sneer at such a low-level and unforgivable tactical mistake made by the opponent's commander, but at the same time he was a little frustrated. If at this time, he has enough manpower, he can quietly move to the enemy's flank, giving them a surprise. But now there are not enough people in my hands.

Since the location of the terrorist was very close to the position of Lin Rui and others, a terrorist commander seemed to have noticed something? Holding the binoculars and looking over here is the hillside.

Having been lurking for a while, Yelena, who was about to retreat, slowly pulled the trigger. She raised the sniper rifle again and patiently waited for the place where the figure was shaking.
