At the post level, committees typically include, but are not limited to:

• Americanism
• Children & Youth
• Education and Employment
• Finance
• House
• Legislative
• Membership & Post Activities
• Public Relations
• Veterans Affairs & Rehabilitation
• Security
• Graves Registration
• Sons of The American Legion

Post committees report and recommend directives to elected post officers who then report and recommend directives to the Post Executive Committee. The Post Executive Committee reports to, works with, and provides directives to the Post Commander, an elected officer, and the Post Adjutant, an appointed officer, and to the post as a whole. Posts provide information and coordinate efforts with District/County leadership. District/County officers, such as district commanders and district executive committees, coordinate, inform and work with posts in specific geographic regions. They then inform and coordinate with Department Headquarters. Departments, also composed of committees and officers, coordinate and work with National Headquarters, which also consists of commissions and committees with specific roles and purposes, an elected national commander and vice commanders, and appointed officers. The National Executive Committee (NEC) is the equivalent to a board of directors of the national organization. The NEC and the National Convention (similar to a stockholders meeting) are uniquely responsible for national resolutions decisions.

At the local level, American Legion posts commonly serve as disaster shelters in times of crisis, working closely with local and state emergency-management and homeland security authorities.
