Which of the following is not a dimension of the Army's professional responsibilities?

The correct answer is that leadership development is not considered a dimension of the Army's professional responsibilities. Within the framework of the Army's professional responsibilities, dimensions such as physical training, strategic planning, and moral and ethical guidance play crucial roles in preparing soldiers for their duties and ensuring they uphold the Army's values.

Physical training is essential for maintaining the fitness levels of soldiers, enabling them to meet the rigorous demands of military operations. Strategic planning involves the ability to formulate and implement plans that align with the Army’s objectives and mission. Moral and ethical guidance is critical because it shapes the character of soldiers, ensuring they conduct themselves in a manner that reflects the Army's core values.

While leadership development is indeed an important aspect of military training, it is not categorized under the core dimensions of professional responsibilities in the same formal way that the other dimensions are. This distinction helps clarify the focus areas that are emphasized for maintaining a professional military environment.
