In World War II, the main force of French 3 million troops guarded maginot line! (France-Germany border, strong base protection! The German attack bypassed Belgium (there is no defense line on the Franco-Belgian border)! British Prime Minister Churchill asked where the French leaders' reserve team was. Answer, there is no reserve! The main force is all on the eastern Franco-German border! Churchill was speechless, and nearly three million troops surrendered to the Germans in January!
The battlefield is changing rapidly, and no clever military expert can fully predict all the deployment of the other side. There is a reserve team to be in case of emergency, and to deal with unexpected situations, we have a greater grasp of victory!
The American army only went to Ganling on the basis of intelligence. It was only because the US military underestimated it at first that it gradually strengthened its strength. After the volunteers came back, they kept sending more troops. No one can retreat in close combat. Only by crustily skin of head, the shells fired by the volunteers in Shangganling are unimaginable to the US military. It is precisely because Shangganling attracted the firepower of the US military that there was no war in other places, which does not mean that other places are not important.
First of all, Hitler's blitzkrieg was effective because he was surrounded by a small country, did not have much defense depth, and succumbed to the powerful firepower of planes and tanks. Not if you meet a big country like the Soviet Union. On the other hand, Italy was seriously delayed, and Germany invested a lot of troops in the battlefield in North Africa. Two fists are hard to beat four hands, and the Soviet Union is vast. We should hold our ground on the eastern front first. Turn to strategic defense and withdraw from the Soviet Union if necessary. Put the main force into the western front and kill the British and American Coalition forces first. Stabilize the occupied areas and provide a lot of logistical support for the front. Focus on the navy and ensure the safety of your oil channel.
It is very important to keep a reserve in the war. If Hitler can keep some troops as reserves, although defeat will not be avoided in the end, it will certainly achieve greater results and may even push the front into France. Although this will not change the outcome of the war, it will definitely delay the time of failure!
It also depends on the situation. For example, both sides 100 people, Party A sends 50 people to keep 50 people as the reserve team, and Party B sends 100 people to keep the reserve team. After World War I, all Party A died, and Party B still had 100 people. Because it was two to one, in the second round, Party A sent out all the last 50 people, but Party B still had 65,438 people.
Li Zicheng made a red eye with Wu Sangui at Shanhaiguan and pressed all the troops up. At the critical moment, the Qing army suddenly came out and caught the Qing army off guard. If Li Zicheng keeps a fresh army as a reserve to deal with emergencies, the result will be unpredictable.
So tactically, the reserve forces are scattered, but strategically, the army also needs a long rest. At this time, the reserve troops will be transferred up, and the combat troops will come down to serve as reserves and have a rest by the way.
In addition, the question of more than a dozen troops you mentioned is actually not absolute, because the deployment of troops takes up space. Let's abstract, imagine the war zone as a line, and then 100 people will be deployed in 10 * 10,1*10 people will be on the front line. If we can deploy by 2*50, we will deploy 50 people.
Reserve, full name, strategic reserve, its main role is not to play a supporting role. Foreign troops are different from us. Foreign officers are influenced by the concept of military school. More than 30% of military casualties are incomplete, which is defined as the loss of combat effectiveness. At this time, reserves are needed to replace the troops with heavy casualties, so this is why there are three establishments at any level of the army. For example, a company-by-company positional warfare is usually deployed in the first line, with one company as a reserve.
China is completely different. Many junior officers have no formal military training, backward equipment, uneducated soldiers and poor military quality. They can't use the reserve team at all. Basically, the reserves are lined up, and some simply take them apart and put them into several battles to refuel. In the end, let alone the reserve team, even their own guard company was sent to fill the pit. Actually, it was a war.
Lin and Su are two styles, the product of specific history and the inevitable result of war. Lin is a clique in the clique, skilled in calculation, flying over Luding Bridge and winning a great victory in Pingxingguan. Later, Siping retreated and went south three times, first south and then north, and then to Jinzhou. Military cadets, equivalent to ace troops, must first calculate the outcome and strive for progress steadily. Su is a breakout member of Jiangxi Red Ten Army, with no rear and no supply. Ten years of life and death are two boundless, and there is no retreat in Gaoyou Campaign and Huangqiao Campaign, ranging from 7000 to 30000. The battle of Meng Lianggu was forced to do nothing. Six vertical batteries are a stroke of genius, which is a far-reaching vision to learn from the war. Xiao Huaihai, the initiator of the Huaihai Campaign, launched the Great Huaihai, which brought the liberation war ahead of schedule. The chairman appointed the first candidate on the Korean battlefield. This is a matter of opinion. You are both military leaders.
Lin Biao saw the soldier's will and his own fight. Su Yu has the nature of gambling, and both have the nature of winning by luck. One can dry up a million bones. The best are Tian Lei and Bin Sun. The value of a general lies in the magic of fighting, attacking the enemy by surprise and winning by surprise. War creativity. Is to beat the other side at a loss, beat the other side to cope, master the initiative in the battlefield, and let the enemy master the passive.
It is common sense to maintain the necessary reserves, but we should also avoid going to extremes and becoming military dogmatism. For example, in the early days of War of Resistance against Japanese Aggression, Chen Xilian of the 769th Regiment of the Eighth Route Army129th Division raided Yangming Fort. Although 24 Japanese planes were destroyed in one fell swoop, and more than 0/00 Japanese troops were annihilated, the results were brilliant, which strongly supported the frontal battlefield of the Kuomintang army's Xinkou campaign, but the tactics were still debatable. At that time, the battle of Xinkou was in full swing, and the deputy commander Xu ordered the 769th regiment to attack Yangmingbao Airport from the rear of the battlefield to support frontal battlefield operations.
Colonel Chen Xilian ordered the 3rd Battalion to attack the airport as a commando, with the 1st Battalion blocking aid and the 2nd Battalion as a reserve. The 3rd Battalion, which is in charge of the assault mission, also arranged for one company to stop aid, and the other company as the reserve team. The battalion commander Zhao Chongde was advancing a company to assault. As a result, a whole regiment is responsible for attacking the airport from the rear (it is unlikely that the enemy will return to the airport in time), but due to careful consideration, a large number of reserves are reserved at the regiment and battalion levels, and only one company has more than 100 people to carry out surprise attacks, which is seriously insufficient. Although after a hard struggle, the assault mission was completed, but his own casualties were also great, and the battalion commander Zhao Chongde also died heroically. Zhao was born in the old Red Army. If you don't die, you will be at least a founding major general or even a lieutenant general in 55 years.
The reserve is a new force. Everyone else is tired of playing, and a new force appears. It is likely to be the last straw to crush the camel. At the Battle of Waterloo, Napoleon sent his own veterans reserve. Prepare to give the opponent a final blow. Is about to win the battle. But Wellington is very lucky. Reinforcements arrived at the critical moment. By this time Napoleon had used up all his reserves. In the end, everyone knows that defeat is Waterloo. Whoever runs out of reserves first loses.
War is the most complicated social activity, and the two sides are playing the most intense game. It also involves unpredictable situations such as astronomy and geography, which are changing rapidly. If we don't keep a strong reserve, it may collapse completely in case of emergency. In the long-term practice of war, people have mastered certain laws of war, and they can't fight without reserve teams.
