Operational Variables are described by which acronym?

• A. PMESII-PT
• B. METT-TC
• C. WARNO
• D. SMEAC

Answer: (A)

Operational variables are described by the PMESII-PT framework. This acronym groups the environment into Political, Military, Economic, Social, Information, Infrastructure, Physical Environment, and Time factors, giving planners a structured way to analyze how different domains interact and influence operations. Using PMESII-PT helps you look beyond terrain and weather to understand aspects like governance, economic conditions, cultural norms, information flows, critical infrastructure, and tempo, all of which shape what is feasible, sustainable, and acceptable during an mission. The inclusion of Time emphasizes how tempo, deadlines, and schedules affect decisions and outcomes, making it a comprehensive lens for assessing opportunities and risks across the entire operational environment. While METT-TC focuses on mission analysis and summarizing factors like Mission, Enemy, Terrain and Weather, Time, Civil Considerations, and is useful for planning, it is not the framework dedicated to describing all operational variables. WARNO is a warning order used to initiate planning, and SMEAC is a format for conveying orders; neither serves as the descriptor set for the operational environment the way PMESII-PT does.
