If there were a hall of fame for modern military theorists, Thomas Edward Lawrence would deserve a place in it. In his dual role of theorist and practitioner of the art of war, Lawrence demonstrated the power of military theory for developing appropriate strategy and tactics in war. In working effectively with the leaders of the Arab Revolt in World War I, he left insights for forging a successful coalition to defeat a common adversary. By embracing the Bedouin Arab way of war, he was able to develop a theory of guerrilla warfare that still holds relevance today. In light of the above achievements, Lawrence should stand as a model for military officers as they prepare intellectually and emotionally to face the challenges of the twenty-first century.
