In this way, the number of personnel on board the navy will remain at about 150,000, and with the addition of logistical support and a small number of marines, the final size of the navy will be maintained at about 200,000, and the combat effectiveness of the navy will be unrivaled after the reform is completed.

The army will be the focus of the next stage of development, after the lessons of this Yangzhou campaign, everyone finally realized that it is okay to rely on 120,000 troops to fight all over the world, but it is not so easy to occupy these places.

Not to mention much, during the war, the administrative units at the county level sent 2,000 defense troops to maintain stability, right? , the whole Great Song Dynasty has 1,234 county seats, and then you will be shocked to find that you need 2.46 million troops just to occupy the county seat by sending all the troops.

Two million is not a joke, there are twenty-six provincial-level administrative units in the Great Song Dynasty, four in Beijing, thirty in government, two hundred and fifty-four in the prefecture, and sixty-three in prison, so you will find that there are not many defense troops of three million.

Just like the current counties in the Great Song Dynasty, there are only dozens of officials who are responsible for catching thieves, or there are one or two hundred Xiang army and civilian regiments, and that's it, and the total number of the Great Song Dynasty Forbidden Army plus Xiang Army and militia groups exceeds three million.

Not to mention, Zhang San wants to occupy Shandong and Hebei, there are about 40 counties, and if he wants to maintain stable law and order, at least 2,000 people must be stationed in a county in the early stage, and 40 is 80,000, so this small 100,000 is gone, and then I think the defense troops of each state capital must be at least 10,000, right?

There are eight state cities here, and there are 80,000 people, and the five closer to the border are 20,000, so that is 130,000, 130,000 plus 100,000 230,000, is this enough? Inadequate!

The Great Song Dynasty will attack, and the Ryukyu Army will defend, not to mention much, the Great Song Dynasty is sending 400,000 troops, and the Ryukyus will send at least 200,000, right? After occupying Hebei, it borders the Liao State, and in order to resist the Liao State, at least 100,000 troops must be arranged on the northern front, right?

And then there should be a little surplus troops left in hand to support the battlefields on both sides at any time, no more than 100,000, right? So the size of the army must reach 630,000 to be enough, how much is 630,000?

The ratio of soldiers to peasants in the Great Song Dynasty is about twenty-five to one, which is still counting the box army, if only the forbidden army is counted, the ratio of soldiers and civilians in the Great Song Dynasty is only more than eighty to one, according to the logistics and productivity of this era, the Great Song Dynasty has been quite developed.

In the first few years, the population of the Ryukyus was only 3 million, and the number of soldiers did reach more than 300,000, which was already an astonishing 10 to 1, which was supported by the looting of the Japanese kingdom, and then the trawling of fishing, plus slave cultivation and guano manure.

During the Great Song War, the Ryukyus barely survived the war by relying on the time when the grain had just been harvested, the army requisitioned grain on the spot, and even equipped the navy warships with small trawls in order to relieve the logistical pressure.

But this proportion of the army cannot be maintained for a long time, if the Ryukyus continue to maintain an army of this size, then it will collapse without others fighting itself, and the ratio of the Ryukyus' maximum conscription is twenty to one.

Once this ratio is reached, the Ryukyus will have to spend all their resources to feed the army, and if the Ryukyus stagnate, the Ryukyus will either start a foreign war or collapse automatically, which is called militarism.

Before the Great Song War, the population of the Ryukyus was only 3 million plus 5 million slaves, while the navy and army mobilized more than 300,000 to the limit, such a load was only launched by the accumulation of three years of Ryukyus, a year of preparation, and the plundering of the Japanese state.

Moreover, in the early stage of the war, there was no shortage of food from Jiangnan, but despite this, in less than three months of the Yangzhou Campaign and a month and a month of the Hangzhou Bay Campaign, the materials hoarded on Sea Shark Island had already consumed eight layers, and the remaining money in the Ryukyu treasury was less than two million yuan.

If you continue to fight, it will really depend on the supply to rob, which is also the reason why Zhang San will accept it when he sees it, of course, not all this money is consumed by the war, and the immigrants also occupy all kinds of resources.

But in any case, the current Ryukyu is almost to the limit, and if it continues to fight, it will overdraw the people's strength, for a country that has just been established, Zhang San still does not dare to do this, and it will not be much to collect taxes in advance.

Moreover, Ryukyu is more like an export-oriented country, and trade is very dependent on exports, and without the market support of the Great Song Dynasty, Zhang San's production cannot be sold, so Zhang San also needs to end this war quickly.

After this war, the number of Han Ryukyu would reach 700 to 8 million, and then the total population of slaves would exceed 12 million, so that Ryukyu would be able to maintain an army of 400,000 men.

The navy has already occupied 200,000, which means that the army can only have 200,000, and the army has 60,000 before the Yangzhou campaign, plus the 30,000 newly trained troops, it is only 90,000.

As for the marines, most of the soldiers will turn into sailors, because they all have a certain foundation in boat management, they can learn faster than re-recruiting, and they can also participate in the battle as jump helpers at critical moments.

Therefore, the army should be expanded from the current 18 regiments to 40 regiments, and the scale of the expansion is still very considerable, of course, 200,000 troops are really not much, so Zhang San had to plan to use the compulsory military service system.

The current military system of the Ryukyus is a model of recruitment, which has a long period of service and retirement, and high personnel stability, so it has more advantages in training tactics and technology, and can be used until retirement after a year of training.

However, compulsory soldiers are different, and the length of service required by soldiers trained in this military system is generally not long, and the maximum length of service after research cannot exceed four years, otherwise soldiers will be resistant.

This kind of soldier trains in the recruit camp for three months, then joins the army and becomes a qualified soldier after half a year to a year of training, and then after three years of hard work, he finally reaches the age of becoming a veteran and an elite soldier, and the time for retirement is up.

In this era, you can join the army at the age of sixteen, and you are only twenty years old when you retire, which is when a person is in the prime of life, which is a waste for the army, and for Zhang San, the return on investment ratio of this kind of compulsory soldier is not very high.

However, the system of compulsory military service is a way to greatly increase the potential of war, and in the case of a limited number of troops, it is necessary to train more soldiers so that they can be used in large-scale battles.

For example, the Ryukyus now plan to recruit 400,000 soldiers, train 100,000 new soldiers a year, and four years later, in addition to the 400,000 soldiers on active duty, there will be 400,000 reserves.

Of course, the navy can't be retired in four years, the navy is more complicated to learn, most of the people are technical arms, so it generally takes at least six years to retire, but with 200,000 reserves in the army, it solves a big problem for Zhang San.
