Which regulation provides guidance on the Army's code of conduct?

The regulation that provides guidance on the Army's code of conduct is AR 350-30. This regulation specifically outlines the principles and responsibilities related to the Army's conduct and ethics. It emphasizes the importance of maintaining military professionalism and integrity, which are critical components of the Army's mission and effectiveness.

Understanding the Army's code of conduct is essential for fostering a culture of honor, respect, and compliant behavior within the ranks. AR 350-30 details the expectations for soldiers and leaders, reinforcing the commitment to uphold the Army values.

The other options do not focus on the code of conduct. For example, FM 7-22 primarily addresses physical readiness training, and FM 4-25.11 deals with first aid and battlefield care, neither of which is related to the ethical and conduct standards of military personnel. Thus, AR 350-30 is the appropriate choice for guidance on the Army's code of conduct.
