“Sounds like a good idea to me”
Extremely bad idea. Army Chief of Staff Marshall forced elderly officers over a certain age to retire in the buildup before U.S. entry into World War Two after the Japanese attack upon Pearl Harbor 7 December 1941. Fortunately, General Marshall made an exception in the case of Colonel George S. Patton and waived the age restriction for him. Col. Patton was promoted in rank to Brigadier General and given the task of organizing the U.S. Tank Corps for the U.S. Army in a desert training center around Ft. Irwin, California. Patton then planned the first major American amphibious invasion with the Allied attack upon French Northwest Africa in 1942. His leadership set the example for future U.S. amphibious invasions in the war.
Blind age prejudice against older military officers without regard to skill, luck, and sheer audacity is extremely harmful to the capabilities of the American armed forces. Any attempt to foolishly squander such human capital on the sacrificial stone of blind and ignorant policy should be and must be opposed with all the derision it deserves.
Retire all the guys with experience and knowledge and replace them with young guys steeped in pop-theories of the day and beholden to whatever politician happens to be in office....
What could possibly go wrong??
