reorganization, that has resulted in a medical command structure curiously similar to that which prevailed before the buildup of US. combat forces. Duplication of efforts in the functional areas of command, including dental and veterinary control, administration, and plans and operations, has been eliminated. Manpower requirements have been reduced without degrading the efficiency of medical operations. More importantly, the responsiveness and flexibility of the command to changes in medical support requirements have improved, perhaps the ultimate test of the value of Army medical service in the theater of operations.

NOTES TO CHART 5
