Which of the following is NOT a characteristic likely to impact future operational environments according to The Army Operating Concept?

The correct choice is based on the context of how the Army Operating Concept delineates the characteristics that will have significant effects on future operational environments. The concept focuses on several transformative trends that are shaping warfare and military operations, emphasizing the importance of adaptability to a rapidly changing landscape.

The proliferation of traditional weaponry does not align with the more dynamic characteristics impacting future operations, as it reflects a more static and established aspect of military capability rather than an evolving trend. The concept highlights areas such as the speed of human interaction (which affects decision-making and tactical responses), advances in cyberspace capabilities (which influence both offense and defense in modern combat), and demographic shifts in urban populations (which relate to where and how conflicts may occur).

In contrast, the other characteristics mentioned represent more contemporary and future-facing dynamics, making proliferation of traditional weaponry less likely to have a transformative impact compared to technological advancements and societal changes.
