The artillery fire of the rì army came very quickly, and the second wave of Ma Run, who had just landed on the mudflat, was immediately blinded. The beach was full of the explosion of shells and the shouts of soldiers. The soldiers shrank their bodies behind the anchored LV2s. Lv2 has a huge drawback - it's too big. Now, however, this disadvantage has turned into an advantage. Lv2's tall body can block more shrapnel. Hiding behind it can dodge a lot of deadly shrapnel. However, it is not a big problem to hide behind these guys for a short time, but after a long time, it is difficult to guarantee that not a single shell will fall directly on the LV. And lv2 is so fragile, the armor is as thin as a layer of paper. As long as a 150mm shell falls inside, the entire LV2 will be blown apart, and the horses hiding behind the LV2 will naturally not have any good results.

Fortunately, the US military planes were still circling over the island, and the shelling of the Rì Army immediately attracted their attention.

"Tommy, look, there's a gun emplacement for the Rì Army below!" Said the driver, Sula.

"I saw it, damn it! How can these rì Ben Yan's gun positions be so scattered! Tommy, who was sitting in the back seat, replied, "It's too much trouble to tell where they are." Vulture calls the eagle's nest, azimuth...... Spot enemy gun emplacements. ”

However, the artillery on Rì's own gun emplacements was not so easy to deal with, and most of these gun emplacements were on the steep rock walls of Oriba Mountain. Rì himself had almost hollowed out the mountain, and in the direction of the sea, many tunnels were dug, some of the larger ones with small openings in the cliff walls, from which Rì's own cannons extended their barrels and opened fire on the beach. ^――Whole site advertising---Welcome to ^^

The American battleships immediately turned their guns around and began to aim at these targets, but it took some time, and during this time, Rì's own shells rained down on the beachhead. Several F4F fighters that took off from the escort aircraft carrier were originally hovering near Oribo Mountain, and after discovering Rì's own artillery, they immediately flew towards these gun positions, and they first fired rockets at Rì's own artillery, but the jīng degree of rockets has always been a problem, and it is good to use them to attack bare unprotected targets, and it is very problematic to use them to attack these gun emplacements hidden in the mountain cliffs. In addition, in order to prevent the plane from crashing directly into the cliff, the pilots could not use the method of approaching about 100 meters to fire rockets to improve the hit rate as they did when attacking tanks, and they could only fire rockets from a distance of seven or eight hundred meters. And in this way, the rockets that shè came out could not hit the target accurately. So although they tried to shoot all the rockets, these attacks did not have much effect, not even to interfere with the shè attacks of the rì army, and rì himself continued to fire at the beachhead.

At this time, the battleship's guns were already aimed at the target, and the F4Fs hurriedly left the shè strike area, and then the giant guns of the American battleships opened fire on the cliff wall.

The shelling of the battleship is not comparable to the rockets mounted on the F4F. High-explosive shells weighing hundreds of kilograms kept falling on the cliff wall, and every shell exploded, causing the cliff wall to shake. However, these shells also did not have enough jīng degrees to directly hit the mouth of the tunnels, so although the shelling was earth-shattering, Rì's own counterattack did not stop. The rìben cannons were still firing at the beachhead. Almost every second, shells fell on the beachhead, and there were also Marines who were injured or even killed in the shelling.

"Order the cruisers and destroyers to approach shè!" Rear Admiral William Brandi ordered.

"General, it's dangerous." A staff officer said to Rear Admiral William Brandy, "If you get too close, you can easily run aground, and if the enemy counterattacks, destroyers and cruisers will ......"

"Execute the order!" William Brandi said.

The staff officer turned and left. William Brandi turned his head to Ron, who was watching from his flagship, and said, "Sometimes, for the sake of your comrades, you always have to take a little risk, don't you say?" ”

"General, you're right." "But it takes a lot of courage to make a decision like that." ”

At this time, the destroyers and cruisers of the US forces approached the coast, and they even advanced to a distance of less than 400 meters from the coast at the risk of running aground and running aground, and then fired at the gun positions of the Rì Army on the cliff wall. Too many ads? Got a pop-up? The interface is fresh, and the whole site is advertised

Compared to the battleships, the cruisers and destroyers had a higher speed, so their guns were still more threatening to the gun positions of the rì army than the battleships, but in two minutes, two of the rì guns were muted. Then the artillery fire of the Rì army quickly fell silent.

"No, we obviously didn't completely destroy all of the enemy's gun emplacements!" General William Brandy made such a judgment.

"Not bad." Ron immediately agreed, "I have inspected some of the German tunnels in Normandy, and the Germans tend to set up a cannon at the entrance of the tunnel, and these cannons can move quickly on the track, and if attacked, they will quickly retreat into the tunnel. It's hard to deal with. I think that the Rì army arranged these gun emplacements on the cliff wall of Oribo Mountain, and they would probably have a similar design. I guess Rì himself probably dragged the cannon back into the tunnel. ”

"Well, I thought so too." William Brandi said. Then he turned around and gave the order: "Let the cruisers and destroyers retreat to a safe area, and the battleships continue to strike at the cliffs...... Ordered the battleship to use semi-armor-piercing shells shè hit. ”

Semi-armor-piercing shells were supposed to be used against enemy warships. But now, the chances of encountering enemy warships are almost negligible. Now the American battleships continued to fire at the cliff wall, not directly destroying the enemy's artillery, but destroying the openings of those tunnels. Semi-armor-piercing shells are more likely to cause the rock on the cliff wall to spit and collapse, and of course they are more suitable for such tasks.

The shelling of the cliff face continued for several hours. Of course, the intensity of the shelling of the American battleships decreased a lot, even though the Rì Army had stopped shelling the beachhead. The rhythm of the shelling also became, the battleship fired one shot, then the school shè plane observed the landing point, sent back the adjustment data, and then the battleship fired another shot.

While the battleship was slowly clearing the exposed tunnel openings on the cliff wall of Oriba Mountain, and firing at the possible tunnel openings, the U.S. Marines took the opportunity to attack. The troops of the 5th Marine Division were the most progressive, their landing sites were subjected to less dense shelling, and Rì himself shelled them a little later than the rest of the area, so they seized the opportunity to attack. On their line of attack, however, was the weakest point of Rì himself, a relatively flat and narrow stretch between Mt. Motoyama and Mt. Oriba at the ends of the island. In the original history, Rì himself did not have time to repair the fortifications here, and in this time and space, because the American army started earlier, the fortifications here are even weaker, almost only a few trenches and civil bunkers. Even the bunkers were not fully built, which prevented their firepower from forming an effective support for each other, and as a result, the Marines quickly solved these things with the help of bazooka and flamethrowers. Then the 5th Division took advantage of the victory and pursued and cut Iwo Jima into two sections in one fell swoop.

Compared to the smooth 5th Division, the 4th Division was more unlucky, they crashed headlong into the well-established fortifications of the Rì Army, and their heads were bleeding. Fortunately, before landing again, the navy also learned some methods of ground-air integrated operations from the army, such as various methods such as ground forces guiding air forces to attack. The Marine Corps is now generally equipped with all kinds of equipment for air communication - radios, smoke markers, fireworks markers and so on. And compared to the army, they also have dive bombers that are more suitable for hitting targets such as pillboxes. After being attacked by machine gun and mortar fire from the Rì Army, the U.S. Marines, who reacted, immediately made contact with the dive bombers of the naval aviation that were already hovering in the air with bombs.

There are 12 escort aircraft carriers in the fire support fleet, and these aircraft carriers have small tonnage and low cost, and are even called "jeep aircraft carriers". Compared to the fleet carriers in the hands of General Spruance who were fishing for fish for his own suicide planes, these carriers were few aircraft, slow, and thinly armored, and they were not a grade at all. Even the things they are equipped with are old goods that have been eliminated by the fleet aircraft carriers. For example, fighter aircraft, fleet aircraft carriers have long been using F4 series things, and escort aircraft carriers are still using old F4F; On the fleet carriers, because the F4 can also be used as a dive bomber, plus the service of the B2 Hell Dive, the old BD Dreadnought dive bombers are transferred to these escort aircraft carriers. Right now, a swarm of BDs is hovering over the heads of the Marines with 1,000-pound bombshells.

Sergeant Bill was lying in a shallow mound of dirt, and not far in front of him was a bunker complex of Rì himself. Machine gun bullets puffed around him, weighing him down.

"Damn it! Who sent shè an indicator to the past! Bill shouted. A few seconds later, he heard a whoosh, a grenade flew past, and a puff of pink smoke rose from the target area.

"At 10 o'clock, there is a target indication! Prepare to attack! Simon, the dive bomber pilot, saw the pink smoke at a glance. So he swooped down with his wingman from a height of 1,500 meters towards Rì's own bunker group at a near-vertical angle.
