What does FM 3-04 refer to?

FM 3-04 refers to the Army's field manual concerning Army Aviation. This manual provides comprehensive guidance on aviation operations, tactics, techniques, and procedures within the Army. It encompasses the various roles of aviation units and how they integrate with ground forces, detailing the operational capabilities and limitations of different aircraft used in the Army. Understanding this manual is crucial for personnel involved in aviation roles, as it lays the foundation for safe and effective air operations, including principles of mission planning, execution, and support for ground troops.

The other choices relate to different aspects of Army operations but do not specifically encapsulate the focus of FM 3-04. For example, while "Army Field Manual" is a correct descriptor of what FM 3-04 is, it lacks the specificity of addressing the aviation aspect that is central to the manual. "Army Vehicle Operations" and "Army Safety Procedures" pertain to different functional areas within Army operations and do not align with the focus of FM 3-04.
