The crisis after 9/11 forced every branch of the military to reevaluate its mission set, its structure, and its identity. Fifteen years later, the process is ongoing. Last week, a congressional report highlighted the debate over whether it should be enlarged or reduced from its current 475,000 soldiers. In that same time, U.S. Special Operations Forces (SOF) grew from a few thousand to 70,000 today. The Air Force expanded its corps of drone pilots and still seeks to double its current number. The changes are far reaching, and the sum total is a military that has demonstrated its plasticity in Afghanistan and Iraq while remaining prepared for its traditional role in conventional warfare.
