Use it or lose it applies to military power. An inactive military is full of opportunists and promotions are based on politics. There is no doubt in my mind that four years of war footing deployment is radically changing the "ARMY OF ONE" into a disciplined and effective fighting machine. Many careers are being enhanced based on performance and the leaders of the future are being forged. Those who serve and leave are also profoundly affected. My mother said my dad learned to pick up his socks in the army in WWII. Yet we hear none of who is distinguishing themselves, even though they will be leaders tomorrow.
I couldn't agree with you more.
