What are the three horizons used by Army units at all echelons for planning training?

• A. Long, Mid, Short
• B. Short, Long, Mid
• C. Long, Short, Mid
• D. Primary, Secondary, Tertiary

Answer: (A)

The idea being tested is how Army units organize training planning over time using three horizons: long, mid, and short. The long horizon sets the overall future plan for readiness, aligning training needs with resources and potential force changes. The mid horizon translates that bigger plan into near-term requirements, sequencing training, and scheduling resources for the coming period. The short horizon then focuses on the immediate window, detailing the concrete training events and tasks to execute in the near future to meet readiness goals. This structure—long, mid, short—keeps planning coherent from years out down to the next few weeks, and it applies at every echelon. Terms like Primary, Secondary, Tertiary aren’t used for these planning horizons, and ordering that places short before longer-range planning doesn’t reflect how the Army arranges training timeframes.
