revolution and roots of war
Revolutionary warfare:
Dragonwars, by J. Bowyer Bell. He is a diffcult read. I powered my way through teh below one, but I have to read it again.
Dynamics of the Armed Struggle, (by the same)
Origin of war:
How War Began, by Keith Otterbein, just barely started.
War Before Civilization, by Lawrence Keeley -- great read. Causes one to question the whole "4GW" concept.
Separation of God and Man:
The Great Divorce, by C. S. Lewis
Team building/leading
The Five Dysfunctions of a Team, by Patrick Lencioni. it has a stupid narrative "parable", but the model he proposes is excellent. It came recommended by a university professor/team builder.
