Query: Spectacular small unit tactics!

Set in the future, but excellent descriptions of small unit tactics and leadership that stand the test of time - past, present, and future. Pay particular attention to the scenario where "doing nothing" (this is an action book!) is the correct choice. Also, this is one of the few fiction books that allows its characters to get tired and have clouded decisions.
