Which of the following is one of the four tenets of Army Operations?

The correct choice is central to understanding the principles that guide Army operations. The acronym METT-TC, which stands for Mission, Enemy, Terrain and Weather, Troops and Support available, and Time available, provides a systematic approach for leaders to conduct operations. This tenet emphasizes the necessity for commanders to assess these critical factors in order to make informed decisions and effectively plan military operations.

By evaluating the mission at hand, the enemy's capabilities and intentions, the terrain and weather conditions that affect operations, the available troops and support, and the time constraints, commanders can develop comprehensive operational plans. This analysis ensures a thorough understanding of the operational environment and the resources available, which is crucial for achieving mission success.

In contrast, the other choices pertain to operational considerations that may support Army functions but do not constitute one of the core tenets that directly impact tactical planning and execution in the field. Logistics and supply chain management, sustainability of human resources, and funding and resource allocation are important components of military operations but are not foundational tenets in the same way that METT-TC is.
