Spearhead of Logistics is a narrative branch history of the U.S. Army's Transportation Corps, first published in 1994 for transportation personnel and reprinted in 2001 for the larger Army community. The Quartermaster Department coordinated transportation support for the Army until World War I revealed the need for a dedicated corps of specialists. The newly established Transportation Corps, however, lasted for only a few years. Its significant utility for coordinating military transportation became again transparent during World War II, and it was resurrected in mid-1942 to meet the unparalleled logistical demands of fighting in distant theaters. Finally becoming a permanent branch in 1950, the Transportation Corps continued to demonstrate its capability of rapidly supporting U.S. Army operations in global theaters over the next fifty years. With useful lessons of high-quality support that validate the necessity of adequate transportation in a viable national defense posture, it is an important resource for those now involved in military transportation and movement for ongoing expeditionary operations.
