I find books on strategy and tactics from other fields help one think about strategy and tactics of basketball.
These are two military histories-one about Civil War generalship, and one about generalship from WWII to present. One completely rearranges your thinking about Robert E. Lee. Another rearranges your thinking about many generals of the post WWII Era. Both do so within the framework of assessing the great troubles generals have identifying effective strategy and tactics. Not much pussy footing around in these histories. About the only knock against them is that they both to some extent make the great mistake of most military histories not written by career military men--they largely overlook, or understate, the logistics that underpinned both the bungling and the astute strategies and tactics examined.
"How the South Could Have Won the Civil War: The Fatal Errors that Led to Confederate Defeat," by Bevin Alexander, Crown Publishers, 2007. Military historian Alexander fills 337 pages with endless examples of Robert E. Lee's screw ups that, had they been avoided, would likely have lead to Confederate victory. Note his focus on Stonewall Jackson's evolution of winning tactics against new rifles and artillery that Lee could not embrace under pressure, where as Northern General Sherman could. Inference: watch out for the little guys, if they ever put a good general in charge, like, say, Stonewall Jackson,or George Washington, they can win wars, not just win battles.
"The Generals: American Military Command from World War II to Today," Thomas E. Ricks, The Penguin Press, 2012. 556 pages of screw ups, where in America moves from an Army that wins wars with politically/strategically astute generals that can be fired to an Army that bungles wars with tactically excellent, but politically/strategically disconnected generals that are never fired. Sobering if true and not just another neocon attempt to cover the trail of their own complicity and so shift blame off them and onto generals in the allegedly bungled regime change wars.
