Brotherhood of War 04: The Colonels By W.E.B. Griffin

In the twilight of a dying decade, a group of battle-hardened professionals comes home to the United States, tasked with forging a new breed of American soldier

They were the professionals, the men who had been toughened by combat in the mine-laden fields of Europe, in Korea, in Greece, in Indochina. Now, they must return to the United States to forge a new type of American soldier—one to be tested on the beaches of Cuba and in a new war yet to come.
