CRS (Congress) · Andrew Feickert, Robert Holcombe ·

Executive Summary

This primer outlines the U.S. Army's five-phase Force Development (FD) process, which translates strategic security requirements into trained and ready forces. It details how the Army designs, authorizes, and resources its units, considering national security strategies, new technologies, and budgetary factors. The process involves determining capabilities, designing organizations, developing models, determining authorizations, and documenting them.

Why It Matters

    Total Army Analysis (TAA) is a process intended to keep the Army within congressional end strength guidance while fulfilling DOD objectives. The Operational Force (OF) TAA shapes the force structure required to meet mission needs.
  • The final phase of force development involves documenting organizational authorizations, which define unit missions, functions, and structures for personnel and equipment requisition.
