Which of the following is NOT a basic inspection principle?

The selection of a casual and informal approach as not being a basic inspection principle is aligned with the need for structured and consistent inspection processes. Inspections are critical to ensure the safety, readiness, and operational effectiveness of equipment and personnel within the Army. They should be conducted with a level of professionalism and thoroughness that the term “casual and informal” does not imply.

When conducting inspections, a focused approach centered around obtaining and providing feedback is essential. This feedback allows for the identification of deficiencies and successes, ensuring that corrective actions can be taken as necessary. Purposeful coordination is equally important, emphasizing the need for organized efforts in managing inspections, including clear roles and responsibilities. Instructive actions are also a fundamental principle, as they guide personnel on how to improve practices and compliance.

Therefore, the correct answer highlights the importance of maintaining a serious and methodical approach during inspections as opposed to one that might overlook critical observations due to a relaxed demeanor.
