The assault force of the Southern Army Land Assault Group, composed of four wings of elite veteran daredevils, all wearing Soviet-style gas masks, with the support of the combat engineer battalion, divided into four attack directions and launched an attack in advance.

The Air Department will send dozens of airships and more than a dozen delta-wing aircraft to provide all-round air support to the attack force. The artillery unit also set up a number of artillery groups, with a total of more than 200 artillery pieces, to provide artillery support for the attacking troops.

Although the support firepower in the Far East was extremely strong, according to the report of the reconnaissance detachment that went deep behind enemy lines, there were almost no living samurai and ashigaru defenders in the forward area of the shogunate defense line, and even those who were lucky enough to die were dying and completely lost their combat effectiveness, and the support units of the air force and artillery did not need to prepare for artillery fire at all.

"Buzz...... Buzz ......" A roar sounded, and dozens of military engineering vehicles roared and rushed out first.

At the forefront are several Soviet-style tracked rocket obstacle breakers, the weapons on these obstacle breakers have been removed, but the vehicles are in good condition, and each vehicle is equipped with a bulldozer, so it has been used as a bulldozer in the Far East, and has been active in various construction sites in the Far East over the years.

After several years of frequent use, the condition of the car is no longer what it used to be. Although the logistics department has been careful to maintain several vehicles, they have long passed their useful life. But Soviet-style weapons are notoriously durable, and they have been used for so long, running all over the ground with the same roar.

The Central Military Commission has specially developed a rocket obstacle breaking bomb, which is imitated from the GBP128 rocket blasting bomb on our army's GSL430 rocket obstacle breaking vehicle. Each vehicle is equipped with 12 GBP128 rocket blasting shells, each rocket blasting bomb can tow a 40-meter blasting rope, and the combination of 12 rocket blasting shells can open up a passage of 480 meters long and 2 meters wide.

Rocket obstacle breakers fire heavy blasting ropes in safe areas protected by infantry, which can blow up low houses in whole columns, and destroy obstacles and barbed wire fences in the defensive line. It can also kill and injure people within a radius, and the cleanup method is very simple and crude, which is better than artillery bombardment, and the cost is extremely low.

"Woohoo...... Woo Woo ......"

Several rocket obstacle breakers rushed to the front of the shogunate coalition forces, and one after another the barrier-breaking rockets were launched with a roar, and the tandem launch units were ignited in turn in the air. Drive the heavy blasting rope to fly forward until the blasting rope is fully deployed, and is straightened in the process of landing by the tension of the control rope, and the blasting rope smashes heavily on the shogunate's defense line, forming a straight explosion belt on the ground.

"Boom...... Rumble......"

There was an earth-shattering loud noise, and the shogunate defense line was suddenly blown out of four passages, and the earthen forts, fortresses and trenches on the defense line, as well as various earthen barriers, fences and large shields and other obstacles were blown up in all directions. In an instant, four forty-meter-long passages were cleared on the shogunate defense line.

Shimazu Tadashi, who was standing in the rear, looked at the sky-high smoke and dust rising from the defense line, his eyes suddenly froze, and he couldn't help but gasp. What kind of firearm is this, how can it be so domineering. He knew best in his heart how difficult it was to break through the defensive line established by the shogunate army, but he didn't expect that the Far East would tear four holes in the defensive line in an instant.

Behind him were the retainer samurai. One by one is also dumbfounded, this is too ruthless. If they let the Satsuma clan attack this line of defense. If you don't die thousands, that's a breakthrough.

One of the family elders suddenly frowned, and asked Shimazu Tadashi next to him: "My lord, the Far East has attacked under the nose of the shogunate army, why haven't I seen the samurai and ashigaru of the Tokugawa family." ”

Shimazu Tadashi and the retainers around him also felt that something was wrong after listening to the words of the elder. They were all shocked by the big killers in the Far East just now. I didn't think about it for a while, but now when I look closely, I find that there is not even a figure on the shogunate defense line, which is also too evil.

Yesterday, they also saw a dense crowd of shogunate samurai and ashigaru, waiting for them on the defensive line. How did it all disappear overnight. Of course, Shimazu Tadashi didn't believe that the shogunate army would retreat at this time, so where did all of them go?

The daredevils who followed the rocket obstacle breaker were all the veteran daredevils who started from the daredevils. He also participated in numerous battles under the leadership of the Far Eastern Military Committee, and saw the powerful artillery fire of the Far Eastern Army. But this time, when they saw four rocket obstacle breakers, they instantly tore through the shogunate army's defenses, which also scared them a lot.

As the dust and smoke cleared, the four wings of daredevils roared along the four passages cleared by the rocket obstacle breakers and smashed into the shogunate lines.

Wearing Soviet-style gas masks and double-barreled shotguns, they carefully searched the shogunate defense line, but what made them creepy was that the bunkers and fortresses on the defense line were all samurai and ashigaru of the shogunate army who had been dead for a long time, piled up there layer upon layer, and everyone seemed to be in great pain when they died, but there was no trace of wounds and blood on their bodies.

These daredevils are all experts at killing people, and they know how they died when they look at the corpses on the battlefield. But they couldn't guess how these samurai and ashigaru on the defensive line died, which also made them feel like their scalps were blowing up, and their backs were wet with cold sweat.

"Buzz...... Buzz ......"

Several rocket obstacle breakers roared up, pushed the remaining obstacles aside with a bulldozer shovel, and then drove to the end of the passage, continuing to launch barrier-breaking rockets to open up a new passage. The military sappers and machinery that followed closely followed, constantly expanding the width of the passage and leveling the ground of the passage to facilitate the passage of follow-up troops.

At this time, more than a dozen airships also flew over, hovering at low altitude above several passages, turning on all the searchlights equipped with the pods to provide illumination for the engineering troops.

With an earth-shattering loud bang, the rocket obstacle breakers that rushed to the front were bombed one after another, and in a very short period of time, they tore apart the defense line that the shogunate army had carefully built for several months, and opened up four passages more than 1,000 meters long.

Other military engineering machinery of the Combat Engineer Regiment also rushed up one after another to clear and level the offensive passages. Four wings of daredevils and two overseas brigades built a line of defense in front of the pass. A total of twenty-four water-cooled heavy machine gun firing positions were established. The artillery unit also moved the firing position forward to the front of the defensive line, ready to provide artillery support to the troops at any time.

Hu Guosheng also came to the defense line and commanded the troops to clear and level the offensive channel as soon as possible, and strive to let tens of thousands of main forces pass through the defense line and attack the enemy in depth in the shortest possible time. (To be continued......)
