Military
Overview
The military is an organized armed group established to defend national sovereignty and territory, and to protect the people and national interests from external military threats. It is generally composed of the army, navy, air force, etc., and each country recruits personnel through conscription, volunteer military systems, or a mixed approach. Beyond being a simple combat organization, the military performs roles in various fields such as disaster relief, international peacekeeping activities, and scientific and technological development, functioning as a core pillar of national security.

History and Development of the Military
The origins of the military date back to ancient civilizations. Professional military organizations existed in Mesopotamia, Egypt, China, Greece, and Rome, used for territorial expansion and defense. During the Middle Ages, knights and lords performed military duties under the feudal system, and the concept of a standing army was established in the modern era. Standing armies, which began in 17th-century Europe, are armies permanently maintained by the state and later spread worldwide. Through the two world wars of the 20th century, the military developed large-scale mobilization systems and advanced weapon systems, and during the Cold War, nuclear weapons and missile technology became central to military strategy. In the 21st century, information technology, drones, and cyber warfare have emerged as new domains for the military.
Military Organization and Rank System
The military generally has a strict rank system and organizational structure. Ranks are divided into enlisted personnel (private, private first class, corporal, sergeant), non-commissioned officers (staff sergeant, sergeant first class, master sergeant, chief master sergeant), and officers (second lieutenant, first lieutenant, captain, major, lieutenant colonel, colonel, brigadier general, major general, lieutenant general, general). Each rank has clearly defined responsibilities and authority, operating on the principle of command and obedience. Organizations are typically formed into squads, platoons, companies, battalions, regiments, brigades, divisions, corps, and field armies, with each unit performing specific missions. Additionally, the military is divided into branches such as the army, navy, air force, and marine corps, and recently, new branches like the space force or cyber command have emerged.
Roles and Missions of the Military
The core mission of the military is national defense, but its roles are diverse. First, deterrence: maintaining strong military power to deter potential enemy invasions. Second, combat operations: engaging and defeating enemies in actual warfare. Third, disaster relief: mobilizing personnel and equipment to support rescue and recovery operations during natural disasters like earthquakes, floods, and typhoons. Fourth, international peacekeeping: contributing to the stabilization of conflict zones through deployments such as UN peacekeeping forces (PKO). Fifth, international cooperation: strengthening diplomatic relations through joint exercises and military exchanges with allies. Sixth, technological development: military technology research has significantly impacted civilian fields such as radar, the internet, and GPS.
Conscription and Volunteer Military Systems
The methods of military personnel recruitment are broadly divided into conscription and volunteer systems. Conscription is a system where the state legally mandates military service for all citizens of a certain age, implemented in countries like South Korea, North Korea, Israel, and Singapore. Conscription ensures a stable supply of defense personnel and fosters patriotism, but it restricts individual freedom and can lead to draft evasion issues. The volunteer system recruits soldiers through selection from volunteers, mainly used in countries like the United States, the United Kingdom, Japan, and Germany. The volunteer system enhances professionalism and voluntariness, but it incurs high personnel costs and may create gaps in defense capabilities if there is a shortage of applicants. Recently, discussions are ongoing about mixed systems combining the advantages of both, or introducing female conscription.
Military and Society
The military has a close relationship with society. Military service is considered a civic duty in many countries and influences individual growth and socialization. Additionally, the military sometimes serves as a channel for social mobility, and in developing countries, it can become an agent of military coups or political intervention. Human rights issues within the military, such as sexual violence, abuse, and suicide, are continuously raised as social issues. Accordingly, reform efforts are underway, including strengthening human rights education, introducing gender equality policies, and expanding psychological counseling services. Moreover, the military accounts for a large portion of national budgets, and the defense industry significantly impacts the economy.
Future of the Military
The future military is expected to change significantly due to technological advancements. Artificial intelligence (AI) and autonomous weapon systems are likely to replace human roles on the battlefield. As drones, robots, and cyber warfare capabilities become more important, traditional troop-centric militaries will gradually reorganize around advanced technology. Additionally, the militarization of space is expanding the role of space forces. Resource conflicts due to climate change and the increase in cyber attacks are emerging as new missions for the military. These changes will require fundamental shifts in military strategy, training methods, and force composition.
Latest Trends
As of 2024-2025, the military is undergoing several changes. First, the introduction of AI and autonomous weapon systems is accelerating. Major countries like the United States, China, and Russia are developing AI-based combat systems and drone swarms, which are expected to fundamentally alter the nature of warfare. Second, the importance of cyber warfare is increasing, leading countries to expand their cyber commands. In 2024, hacking attempts by North Korea and Russia increased, prompting strengthened international cooperation to counter them. Third, the militarization of space is becoming a reality. The U.S. Space Force tested a new satellite interception system in 2024, while China and Russia are accelerating the development of space weapons. Fourth, discussions on conscription are active. In South Korea, debates continue over the decline in military service resources and the introduction of female conscription, while in Europe, several countries are considering reinstating or strengthening conscription following Russia's invasion of Ukraine. Fifth, improvements in human rights and welfare within the military are being emphasized. Militaries worldwide are introducing policies to eradicate sexual violence, support mental health, and increase diversity. Sixth, climate change is affecting military operations. Military responses are being discussed to prepare for base damage from extreme weather, threats to naval bases from rising sea levels, and increased resource conflicts.
