Final answer:
Having an on-hand supply of ammunition can be a strategic measure for establishing a requirement or receiving authorization. This practice ensures preparedness and continued capability in unpredictable circumstances, reflecting a historical and strategic approach to securing necessary resources for military activities.
Step-by-step explanation:
Whether having ammunition supply on-hand justifies establishing a requirement or receiving an authorization is informed by strategic considerations of national security and military logistics. The United States has a history of stockpiling essential materials for wartime use, as evidenced by the U.S. Defense National Stockpile Center which holds reserves of materials critical for weapon systems. The ability to continually obtain key products is vital, and stockpiling can serve as a precautionary measure to ensure that the military is prepared, even with unpredictable supply chain issues. This is similar to historical approaches as noted by famous theorists like Sun Tzu, who emphasized the importance of being prepared with material for raising fire, and also by President Wilson, who knew that wartime success depended greatly on preparation and securing resources like men, money, food, and supplies.
