The Russian-Ukrainian War is a classic example of a modern national-level multi-dimensional war. The Russian-Ukrainian War not only gave countries the opportunity to observe various changes in modern warfare, but also could verify their own military theories and combat methods.

This month, the US Army has officially issued the FM3-0 version of the Army Operation Manual, which is a completely new change in the Russian-Ukrainian war experience. Among them, it reflects the five key points of the war. Which side has the five elements, which side is likely to win.
First of all, military operations are almost no longer hidden in modern warfare. There are reconnaissance satellites everywhere, early warning aircraft , reconnaissance aircraft , drone , and smartphones that can take photos and videos everywhere, and even ubiquitous surveillance probes. In fact, there is no secret to military operations.

On the battlefield, most of the actions are carried out under the surveillance of the opponent. For example, in , the Russian army organized multiple hidden mechanized column raids. All of them were exposed to the Ukrainian army through smartphones and roadside monitoring systems along the way, resulting in the Ukrainian army setting up an ambush in advance and the Russian army failed many raids.
Therefore, modern military operations must be a goal, decentralized operations must be closely coordinated, and small units covertly dispersed operations to avoid being targeted by heavy weapons. Concentrated troops and stationary troops are both targets and must act dispersedly and maintain a mobile state.

Secondly, the firepower unit must be dispersed, precise and long-range capability. Joint task forces that strengthen space, network, intelligence combat capabilities and have long-range precision strike forces. It will be able to operate in a wide battlefield, disperse and strike independently, and closely coordinated with various fields in land, ocean, space, network and air to accurately strike opponents from a long range.
is actually a scattered maneuver long-range fire strike unit that can accurately strike from different locations to targets that appear in real time under unified command. And the opponent doesn't even know where to fight back.

Again, Milford Bigg, director of the U.S. Army Command and Staff Academy, said that modern warfare is transparent, so there is no longer a continuous front, but a decentralized battle. At the same time, we must have the ability to coordinate and control the various nodes on the battlefield, and re-converge these dispersed forces in multiple decisive locations.
Fourth, modern warfare ground war is no longer a simple ground war, simple air support. Instead, each military service can fight together. For example, an air force fighter can discover an air defense missile position through the advanced radar . Pilots can discover more suitable units around the attack from the joint cooperative combat system and notify a ground self-propelled artillery to strike a 40-kilometer-long air defense missile position.

Modern battlefield strike speed increases exponentially, and all participating units must maintain high-speed combat status on the battlefield. For example, while engineers clear obstacles, drones must monitor the war zone 24 hours a day, and each self-propelled artillery team maneuveres within a range of hundreds of kilometers to carry out long-range precise strikes at any time.
Tank enters the starting position behind the front line, and the infantry begins to enter the battlefield. A full-process, fast-paced offensive battle was launched around collaborative attacks, sweeping away barriers, and snatching control in depth. This kind of combat requirements are extremely high for command link control, coordination of troops, intelligence collection and acquisition, firepower strike and damage.
Fifth, in modern warfare, powerful long-range precision strike weapons can strike targets hundreds of kilometers or even thousands of kilometers away. In space, sky and ground detection systems can monitor almost any combat operation. Under such long-range strikes, the opponent's weapons and supplies cannot even be transported to the battlefield through the rear railways and ports. Therefore, long-range precision strike weapons and multi-dimensional air defense and anti-missile systems must be available.

Whoever can better grasp the five elements will have more chances of winning. Scatter the enemies on various small units that appear in real time on the battlefield and carry out accurate strikes in the first time. Carry out long-range destructive strikes on the opponent's deep regional strategic and tactical goals in the rear, etc.
