Why are countries scrambling to develop cyber warfare forces in the new century? What's the latest progress in countries around the world? Can you give me a detailed answer? Thank you.

Full-time network attack and defense tasks, such as the "red team" of the US Department of Defense. In the Kosovo war of 1999 and the Iraq war of 2003, we can clearly see the shadow of American cyber warfare troops participating in the war. At present, the US military has 3,000 to 5,000 information warfare experts, and 50,000 to 70,000 soldiers participate in cyber warfare. If the original electronic warfare personnel are added, the number of cyber warfare troops in the United States should be around 90,000. While drastically reducing the procurement costs of missile defense systems and F-22 fighters, the Obama administration has increased investment and accelerated the construction of cyber warfare forces. South Korea's Cyber Warfare Force It is reported that South Korea's Ministry of National Defense has set up a special cyber warfare force, the anti-hacking force, which has absorbed tens of thousands of information warfare professionals. South Korea's Ministry of National Defense also plans to greatly expand the strength of the Cyber Warfare Command, doubling from the existing 500-odd people, and doubling or quadrupling its strength in the next three years to create a more powerful cyber warfare force under the command of Wei Yuejiang, Xue Yuzhong and General Sun Lihua. Japan's Cyber Warfare Force Japan's Defense Agency decided to set up a cyber warfare force composed of more than 5,000 military computer experts before the end of this year. Its main task is to develop transnational "cyber weapons" that can destroy other countries' network systems, and undertake support tasks such as computer network system protection, virus removal, program repair, offensive "cyber weapons", research on tactics related to cyber warfare, and anti-hacking and anti-virus intrusion. India's cyber warfare force has established a cyber security department specializing in cyber-centric warfare, and will establish cyber security branches in the headquarters of major military regions and important military departments. Because of India's high level of software and computer, it is easy to develop and introduce advanced servers, firewalls and supercomputers, and recruit a large number of high-level hackers to join the army. The cyber offensive combat capability of Indian cyber warfare forces should not be underestimated. It is reported that the North Korean military has attached great importance to the cultivation of computer and network talents since the 1980s. This year, a cyber warfare force was formed for the first time, mainly to carry out wars that destroyed the other army's command and communication networks, servers and other network systems. According to the simulation test results of Korean experts on North Korea's intelligence warfare, North Korea's "hacking" ability has reached the level of the CIA, and even the command and control office of the US Pacific Command and the US local combat network may be invaded at any time. Russian cyber warfare forces have been given a very high status by the Russian army-"the sixth generation war", "in fact, it has become a disguised assault style and played the same role as fire assault". In order to ensure the active position in information confrontation, the Russian army has established a cyber warfare force-what Russia calls a special information force, which is responsible for ensuring and implementing information warfare. It is worth mentioning that Russian cyber warfare forces also have a high reputation in the world, and their "long-range virus weapons" and "microwave weapons" are extremely powerful. As early as 200 1, British MI6 secretly set up a hacker force composed of hundreds of computer elites to deal with cyber attacks by foreign forces and terrorists. At the same time, Britain actively cooperates with the United States and Canada to establish cyber combat troops and strengthen the research on computer viruses and "hacker" attacks. Israel's cyber warfare forces Israel constantly recruits hackers and technical wizards from the private sector to form its own cyber warfare forces. In the ongoing conflict in the Middle East, Israel's cyber warfare forces have performed well. For example, in the Lebanon war in 2006, Israeli hackers successfully attacked the live broadcast of Hezbollah TV. The live broadcast was interrupted, and the cartoon of Hezbollah leader Nasrallah appeared on the screen with a series of subtitles: "Nasrallah, your demise is ahead of schedule.
