What are the operational variables (PMESII-PT)?

• A. Political, Military, Economic, Social, Information, Infrastructure, Physical Environment, Time
• B. Political, Economic, Social
• C. Geography, Weather, Culture
• D. Logistics, Force Structure, Communications

Answer: (C)

PMESII-PT is an analytic framework that divides the operating environment into eight domains to show how different factors shape planning and execution. The eight domains are Political, Military, Economic, Social, Information, Infrastructure, Physical Environment, and Time. Each domain guides what to look at when assessing how a mission might unfold: political factors affect governance and legitimacy; the military domain covers armed forces and security; economic factors involve resources and budgets; social concerns include demographics and cultural norms; information covers messaging, media, and cyber aspects; infrastructure looks at networks, utilities, and critical systems; the physical environment includes geography, terrain, and climate; and time accounts for tempo, sequencing, and deadlines.

Geography and weather fall under the Physical Environment, and culture sits under the Social domain, but they don’t by themselves constitute the full set of operational variables. PMESII-PT requires considering all eight domains to capture the complete picture for planning and decision-making. So the standard answer is the eight-domain set above, not just Geography, Weather, Culture.
