Soldiers have more operational flexibility against a myriad of state and non-state actors. Enlisted personnel are less likely to specialize but receive more varied training in ground combat, clearance operations, paratroop experience, extraction, etc. Officers become more specialized, and then teach those under their command on the job in different environments. Traditional military structures are transformed. For example, instead of an Army, Air Force, and Navy, some nations move to a Reaction Force (high readiness, light force), Prevention Force (heavy force used for deterrence) and Integration Force (joint military-civilian, multi-agency force).
