The United States Army is a complex and multifaceted organization, comprising various branches, specialties, and roles that work together to achieve its mission. With over 470,000 active-duty soldiers, the Army is the largest branch of the US military, and its personnel play a critical role in defending the nation and its interests. In this article, we will explore the different roles in the Army, their responsibilities, and the skills and training required to perform these roles effectively.
Commissioned Officer Roles

Commissioned officers are the leaders of the Army, responsible for planning, directing, and executing military operations. They are divided into several branches, including infantry, armor, artillery, engineering, and logistics, among others. According to the Army’s personnel data, there are over 90,000 commissioned officers serving in the Army, with the majority holding the rank of lieutenant or captain. Each branch has its unique responsibilities and requirements, but all commissioned officers share the same core values of leadership, integrity, and selflessness.
Infantry Officer
An infantry officer is responsible for leading infantry units, which are the backbone of the Army’s ground combat forces. They are trained to conduct a wide range of missions, from urban warfare to counterinsurgency operations. For example, during Operation Enduring Freedom in Afghanistan, infantry officers played a crucial role in leading patrols and conducting raids against enemy forces. Infantry officers must possess strong leadership skills, physical fitness, and the ability to make quick decisions in high-stress situations. A study by the Army’s Center for Army Lessons Learned found that infantry officers who had received training in adaptive leadership and decision-making were more effective in combat situations.
