It is interesting to say that the origin of the Katyusha was that the Soviet Union trained a group of fighters to operate this weapon, but due to the high level of secrecy, the fighters did not know the name of the weapon at all.

Then they associate the "K" on the artillery with the Soviet popular song "Katyusha", the lyrics of which tell the story of a girl named Katyusha, whose lover left her hometown, left her side, and went to the battlefield to defend the frontier.

And Katyusha is also a common name for Soviet girls, so the soldiers affectionately called this gun "Katyusha", and over time, this name has been handed down.

How powerful is this rocket launcher? His weapon system consisted of a launch frame consisting of eight I-shaped launch rails, each of which could hold two M-13 132mm rockets at the top and bottom. It is especially suitable for striking exposed dense enemy forces concentrations, field fortifications and cluster tank artillery

Each Katyusha rocket launcher is equipped with 16 rockets at the same time, which can fire all 16 rockets in 10 seconds, with a maximum range of 8.5 kilometers, and can form a terrifying dense strike fire in a short time.

Because the stress effect of high bore pressure and high acceleration of the rocket launched by the barrel is avoided, the acceleration of the rocket launched by the guide rail is small, and the wall of the rocket can be made thinner, which increases the amount of explosive filling.

As a result, the power of 132-mm rockets is basically equivalent to that of ordinary 152-mm artillery shells, which are very suitable for striking exposed enemy concentration areas, field fortifications and cluster tank artillery. It takes only 5-10 minutes to reload after a salvo, which greatly improves the combat efficiency of the battlefield.

Moreover, in the later period, the Katyusha adopted the American GMC type 6X6 truck chassis, and its performance was better than that of Soviet trucks. The truck is equipped with a GMC-type 6-cylinder engine with a power of 91.5 hp, which improves the maneuverability and maximum travel of the rocket artillery, allowing it to run at speeds of up to 70 kilometers per hour on flat roads.

One can imagine that a rocket artillery division composed of hundreds of Katyusha can launch nearly 2,000 rockets in just one minute if it strikes at enemy targets at the same time.

Each of these rockets was equivalent to a 152-caliber howitzer, and a dense barrage of nearly 2,000 rockets could all fall on the enemy's head in just a few tens of seconds.

What "Miss Germany", "American Tiger Girl"... In terms of the degree of firepower coverage, they are all scum in front of the "northern girl Katyusha", and Krupp's big Hanhan is estimated to have to sleep with it in his arms at night after seeing the power of the latter.

The only drawback is its limited range, which makes it extremely vulnerable to enemy artillery fire if the firing position on the battlefield is not concealed enough or if it is detected in an artillery position. Therefore, the rocket artillery units all left immediately after firing one or two rounds, taking advantage of the mobility advantage of the trucks to fight and withdraw quickly, without giving the other side a chance to counterattack.

And then there is the fact that this thing is very professional, and the illiterate mud legs can't play with her, even experienced artillerymen have to go through a long period of training to be proficient in operation.

"Looks like we're going to have to plan a training policy for this weapon..."

Liao Mingyu touched his chin and pondered for a moment, and then said to the system: "Exchange 24 Katyusha rocket launchers, let's form a rocket artillery regiment first, it's a big deal to recall a group of artillery for intensive training when the time comes." ”

"Ding... BM-13 rocket artillery is exchanged for 1500 points, 132 mm rocket artillery is exchanged for 100 points per unit, and a single rocket carries 16 rockets for the first time, the total exchange price: 74400 points, and the remaining points are 460321. ”

Good guys, 24 Katyusha actually cost more than 70,000, and these 384 rockets are 38,000, and proper ammunition is more expensive than artillery, and this is only the price of basic ammunition.

Liao Mingyu smiled bitterly and wanted to cry without tears, just one salvo would have to burn tens of thousands, it seems that this thing can't be squandered unscrupulously.

But when I think of the scene that is like a thunderstorm destroying the world, it seems that all this is not so distressing, and it is worth it to let the little devil taste this taste.

Thinking that the 21st Division of the Volunteer Army, which was equipped with 120 Katyusha rocket launchers, it was the old crying father and mother of the United States on the Stick Peninsula, and achieved its own prestige as the "Terminator of the American Army", and at the same time, the 21st Division became a nightmare that they will never forget.

……

At the same time, thousands of miles away in Singapore, in a small milky white European-style western-style building, several old men in long robes are sitting upright on chairs, and it can be vaguely seen from their cloudy faces that something big is about to happen...

"Master, the Japanese are now vigorously arresting rebels from all walks of life, the Li family and the Huang family have been arrested a lot, and even the intelligence team is hiding in XZ itself, so we still have to make plans as soon as possible..."

One of the middle-aged men looked anxiously at the old man on the first seat, and his anxious expression was fully revealed.

The old man had a tuft of goatee, his white hair was combed naked, and he was at least eighty years old.

His eyes were slightly closed, but there was no joy or anger on his thin face, but the constantly beating eyeballs under his eyelids showed that his heart was not calm at the moment.

"Sir?" Seeing that the other party didn't speak, the middle-aged man asked in a low voice again, and the iconic hooked nose after raising his head was impressive, and it was the extraordinary housekeeper who followed Fang Jingyao at the beginning... Agui.

The old man raised his arm and waved his hand back, and several servants behind him bowed down and exited the room, and closed the door tightly with great interest.

This old man who leaned on the chair and had no energy was the previous generation of the Malaysian Fang family... Fang Chongen.

Ah Gui looked at the few servants with gray hair and trembling when they walked, and he couldn't help but sigh.

In the huge courtyard, there are only a few old men who are older than themselves taking care of the head of the family, which is really uncomfortable.

Originally, their Fang family was a giant in Singapore, and they were all in the business world, but unfortunately everything came to naught after the arrival of the Japanese, and Wanguan's family property became a poison that caused death.

Not only the Fang family, but also in the past few years of the Japanese invasion, several major Chinese families in Nanyang have been wiped out, dying and fleeing, and some clansmen have been almost slaughtered, less than one of the ten who survived, and the glory of the past has long been gone.

The old man was about to straighten up from the chair with his cane, and the middle-aged man hurriedly came up to support him:

"Master, watch out for your body, you should lie down."

"Out of the way, alas... Agui, I don't know how Jingyao is doing in Myanmar? We've got quite a few of those lads left. Old Man Fang slowly opened his eyes, and some things gradually aroused his thoughts in his mind.

"The second young master is very good now, he has served as the chief of staff of the division in the 88th Army of the Expeditionary Force, that general values him very much, and the brothers of our self-help army have also formed a division with the help of that general, and they are killing Siam in front of him."

Thinking of the current development of the Self-Salvation Army, Agui couldn't help but praise, although the process was a little tortuous, the 50th Division formed by the Self-Rescue Army as the main body was not under the control of Fang Jingyao, but at least Liao Mingyu was also benevolent and righteous for them, without the latter's help, this wave of people would have died in the forests of southern Myanmar a long time ago.
