Introduce several combat defense systems.

As we all know, troop deployment, firepower distribution, position distribution and obstacle distribution are the four basic elements in the defense system. With the transformation from mechanized warfare to information warfare, these four elements have also changed from time to time, and the following obvious development trends have appeared.

The deployment of troops ranges from "echelon fixed combination" to "module random elastic combination"

In mechanized warfare, the troops deployed in defensive operations are mainly deployed in echelon mode. For example, teachers and soldiers are often organized into two echelons, which are organized into reserve teams, cover teams, reconnaissance and attack teams, rear defense teams and other arms and support groups (teams). Each echelon is usually dominated by a certain arm and supported by other arms (sub-units). Once this "bundled" force combination mode is determined, it will not be easily or easily changed. Its main advantage is that it can produce sustained and stable resistance, and it is particularly powerful against the procedural attacks of the enemy step by step.

In the future information war, because the attacker often has strong battlefield maneuverability and reaction ability, he can change the main attack direction and force formation at any time. In this case, if the defender wants to suit the remedy to the case, he must break the traditional "parallel" fixed combination mode of the echelon, adopt the method of system integration, randomly combine and decompose various combat units with different functions according to the changes of the enemy's situation and the different targets he defends, give full play to his own synchronous combat ability, "take quick action" and change the strain, so that he can always form the greatest resistance to the enemy's attack points.

The fire distribution system has changed from "pre-planned layer-by-layer application" to "relying on the network for real-time attack"

In traditional defensive operations, due to the dense fog in the battlefield, defenders often can't grasp the changes of the battlefield situation in real time, so they can only plan the fire distribution system in advance according to different goals and combat seasons. When a higher level of fire support is needed, hierarchical application is often time-consuming and laborious. For example, the distribution of firepower to the ground usually consists of attacking and assembling, approaching and expanding the enemy's firepower, resisting the enemy's impact firepower, preventing the enemy from encircling and attacking the firepower in depth, supporting the elimination of the invading enemy's firepower, and attacking the enemy's important targets in depth; The air defense firepower distribution system usually consists of firepower to prevent enemy aerial reconnaissance, firepower to shield defense forces against enemy attacks, firepower to shield anti-attack and anti-attack, firepower to reduce aircraft with infantry and tank soldiers, firepower to shield rear deployment and firepower to be sent back and forth. Although this traditional planned firepower will lag behind the actual changes in combat operations in the era of mechanized warfare, it is usually more reliable and effective because of the slow pace of combat at that time, and the attackers often carry out operations according to the procedures of assembly, approach, deployment, impact, circuitous encirclement and deep attack.

In the future information battlefield, the attacker will carry out flexible, all-round and all-depth attacks in the vast battlefield space. If we still fight in the traditional way of planning firepower in advance and applying for reports at different levels, it will be difficult for the defender to adapt to the ever-changing battlefield situation. Therefore, giving full play to the role of information technology, especially C4ISR system, integrating all firepower units into an integrated real-time coordinated firepower strike system, and seamlessly linking with campaign and even strategic firepower strike systems, and at the same time maximizing the self-synchronous strike capability of all firepower units, relying on network systems to improve the maneuverability and flexibility of firepower strikes, realizing random coordination and on-call, and exerting the maximum overall strike force at the fastest speed will be the development choice that the fire distribution system of defensive operations must make.

The position system has changed from "digging and sticking to a fixed defensive zone" to "flexible disposal because of the enemy"

Throughout the ages, defensive operations have been formed on the basis of certain positions. In mechanized warfare, the arrangement of this platoon is mostly built in a fixed defense area, and it takes a lot of manpower and material resources to establish various positions. Although there have been changes from trench position system, support position system to defensive position system, the basic feature of this platoon arrangement is to stick to the area.

In the information war, on the one hand, due to the surprise attack and the improvement of attack power of the attacker and the enhancement of battlefield mobility, it is necessary to build a relatively perfect position system anytime and anywhere; On the other hand, the rapidity of combat makes it temporarily impossible to build a perfect position system with traditional methods. Therefore, in order to solve this contradiction, the defender has to seek the method of "having both fish and bear's paw": it can not only complete the position matching in a short time, but also have high protection ability. The wide application of computer simulation technology undoubtedly provides the possibility to improve the temporary strain speed and effect of position system. It can be seen that the extensive use of microcomputer processing system enables the defense side to store the important terrain data, damage probability, position and compilation scheme of all important directions and regions in the pre-established position construction model at ordinary times, so as to call out the terrain matching data of the pre-established position and various corresponding construction schemes at any time according to the enemy's attack direction, assault target and the changes of their own defense emphasis, direction and task in the battle. With the help of efficient construction machinery, various advanced blasting methods and rapid concrete solidification methods, we can build corresponding positions in new defense directions and lots in the least time, and improve the adaptability of the position system as much as possible.

Obstacle collocation is mainly from "preset" to "random placement"

In traditional operations, the attacker mainly uses tanks and armored vehicles to break through the ground, which is greatly affected by terrain conditions and has a slow maneuvering speed. On the one hand, defenders can roughly judge the enemy's attack route in advance, on the other hand, it takes a long time for the enemy to attack the defense line, which provides favorable conditions for setting obstacles on the enemy's attack route in advance.

Under the condition of informationization, because the offensive party's maneuverability, especially the air maneuverability, is greatly enhanced, the breakthrough speed is greatly improved, and the breakthrough direction is flexible and changeable. Only when the defensive side's obstacle setting is mainly temporary maneuver setting, supplemented by preset, can it be targeted and improve the blocking ability.
