"We are all sharpshooters, every bullet destroys a guard, we are all flying troops, even if the mountains are high and the water is deep.

In the dense woods, there were camps for comrades everywhere, and on the high hills, there were countless of our good brothers.

There is no food or clothing, and the enemy has sent him forward, and there are no guns or cannons, and the enemy has made us ......."

Horn and horn, when the singing stopped, Yi Zi'an applauded himself, and then asked: "Well, Lao Pi, can I take out my "Guerrilla Song" for a concert?" ”

Pixiu patted the ear position of the helmet and complained mercilessly: "Unless you give everyone the money to treat the ear in advance, it is about the same, I don't believe you ask Lao Zhang." ”

Zhang Yumin on the side scolded with a smile: "You two are cheap, you can't see each other, and you won't be happy if you don't play tricks." ”

According to the battle plan, the three of them were assigned to the 15th Guerrilla Combat Group, the 5th Column, the 9th Guerrilla Corps, the 6th Detachment, the 3rd Brigade, and the 10th Squadron, serving as squadron leaders, squadron staff officers, and intelligence and communications liaison officers.

According to the sequence, the numbers were 150509060310, and later on the map of the distribution of the guerrilla fleet, this string of codes was displayed.

The three men had ten squads under their command, totaling 10,000 and 200 warships, but they could only manage themselves, because one squadron had three combat commanders.

More than 20 billion warships, accounting for 8 percent of all warships in the expeditionary force, although mainly light high-speed battleships and patrol ships, but also a force to be reckoned with.

The guerrilla command is subordinate to 20 guerrilla groups, each of which is subordinate to ten columns, and under the column there are ten general units, which according to the decimal system, are detachments, brigades, squadrons, and squads.

The division was too open, and a large number of unmanned spacecraft could only be used to form each squad, and the squadron command group was only three people, and even so, all guerrilla groups were equipped with nearly seven million people.

You must know that the entire expeditionary fleet is only 130 million people, and this will deduct more than 20 million scientific research and production personnel.

Although at a critical moment, these scientific research and production personnel can also undertake combat missions, after all, they have received complete and systematic military training and passed the assessment, but it is too wasteful to push scientists to the front line.

"All guerrilla squadrons, please note that the squadrons that have completed the formation will set off directly and go to the predetermined area to carry out combat orders in the planned direction."

Hearing the order on the radio, Yi Zi'an put away his smiling face, and said after taking a long breath: "Brothers, sit down, we are leaving!" ”

The command ship of the three of them is a high-speed ship of one million tons, and thirty-six strategies are the best policy, what they want is one leg fast, and the others are floating clouds.

"Let's go, stop grinding." Pixiu slapped Yi Zi'an in the face.

"Look at your urgency!" After making a joke, the more than 10,000 warships belonging to Yi Zi'an's squadron turned around and flew diagonally upward.

At present, the expeditionary force is still more than two hundred light-years away from the target, of course, this is a straight-line distance, and the range is close to a thousand light-years.

The speed of the main force is maintained at the speed of three hundred lights, and it will take three years to fly over, but the Green Rain Republic will definitely not allow the Huaxia fleet to drive directly into it, and many obstacles on the road are indispensable.

The further you go, the more interceptions there are, and no one knows how long it will take.

"According to the battle plan, our squadron needs to fly 60 degrees upwards and fly 500 light-years, and then depending on the situation, fly a certain distance horizontally, or turn down 60 degrees to fly 500 light-years, at least 1,000 light-years......"

Before Yi Zi'an finished speaking, Pixiu directly interjected: "This is still a straight-line distance, the voyage is estimated to be three thousand light years, and our fleet is a thousand times the speed of light, and it is estimated that it will take about three years to go around the rear of the green rain, and I don't know if it will be in time." ”

Zhang Yumin answered: "What do you think of my proposal?" According to the designated route, take a shortcut and strive to reach the designated place within one year. ”

Hearing Zhang Yumin's proposal to take a shortcut again, Yi Zi'an and Pixiu couldn't help but feel a little moved.

In the universe, there are roads everywhere, as long as there are no super-large gravitational stars such as white dwarfs and black holes, or natural disasters such as supernova explosions and red giant expansions, they can fly.

Moreover, guerrilla warfare stresses mobility and flexibility, and the so-called operational plan is only of a guiding nature, and is not mandatory.

When there is no clear combat goal, the three can independently make a plan according to the actual situation.

"We calculated the area that Green Rain actually controlled in terms of a hundred light-years, and assumed that the star system in which it was located belonged to the same plane as our fleet, and we flew upwards.

In this way, the route is saved by nearly half, and it will definitely be able to reach the rear of Green Rain before the main force starts a large-scale battle. Zhang Yumin explained while doing mental arithmetic.

Yi Zi'an and Pixiu glanced at each other, and finally couldn't hold back their hearts, looked at each other and nodded, and made up their minds.

Yi Zi'an clapped his hands suddenly and shouted: "That's it, I will inform the brigade of the new plan, and you will sign it." ”

"Good!" Pixiu and Zhang Yumin spoke in unison.

Soon, the approval of the brigade command was received, and their plan was agreed.

As a result, the fleet adjusted the deflection angle of the course again and inserted it towards the Green Rain Republic.

At the same time, all the fleets under the 150509 Corps changed course synchronously, maintained a general plane with Yi Zi'an's squadron, and flew towards the rear of the Green Rain Republic.

Of course, there is no front, back, left, right, and bottom in the universe, and these concepts are still derived from the inherent biological cognition of human beings, with the head up, the feet down, the face forward, and the back back.

When all people use such biometric direction descriptions, there is no problem.

But after all, the universe is three-dimensional, and when the distance is too far, the direction will naturally be disordered, so the universal coordinates are still the ecliptic coordinate system.

The ecliptic plane refers to the plane of the Earth's orbit around the Sun, and the angle to the Earth's equatorial plane is 23°26'.

Because the gravitational pull of celestial bodies such as the Moon and other planets affects the Earth's orbital motion, the position of the ecliptic plane in space is always irregular and continuous.

But in a fluctuating motion, at any one time, this plane always passes through the center of the sun, and the great circle where the ecliptic plane intersects the earth is called the ecliptic.

The ecliptic coordinate system is a coordinate system based on the ecliptic plane, which can meet the needs of use in most cases.

"Mr. Wang, all the guerrillas have set off, and most of them have changed their routes in the original guidance plan, and a few of them have been rejected." Liu Jinlong reported to Wang Dao.

Wang Dao nodded and ordered: "Well, I have already seen it, inform the main fleet to raise its vigilance, and don't let the fleet of the Green Rain Republic break in again." ”

Everyone was unwilling to fly over step by step, especially some of the ones that were too long, so they all chose to take a shortcut.

However, some are too radical, such as flying directly over in parallel, isn't this just a headlong crash into the opponent's base camp, and it must be dismissed.

Woo-woo-woo-

The poignant and piercing battle alarm suddenly sounded, another enemy fleet appeared, and a new battle was about to begin!
