What factor determines that officer and enlisted interactions are prejudicial to good order and discipline?

The correct answer focuses on the aspect of objectivity being compromised. In military settings, maintaining clear boundaries between ranks is essential for ensuring good order and discipline. When officer and enlisted interactions lead to a loss of objectivity, it can produce biases that affect decision-making, evaluations, and the overall command environment. This lack of impartiality may result in favoritism or perceived unfair treatment, which can disrupt cohesion and morale within a unit.

Although other factors such as personal relationships and performance reviews are significant, they primarily come into play when objectivity is already compromised. The essence of military structure relies on the clear delineation of rank and responsibility; if those interactions blur that line and question objectivity, it fundamentally undermines the principles of leadership and accountability in the force.
