A program designed to test objectively and evaluate quantitatively the cross-country mobility of the Overland Train (a logistical cargo carrier) in a desert environment was conducted over selected courses at the U. S. Army Yuma Proving Ground. The following data were collected within each terrain type occurring along the courses tested: fuel consumption, electrical energy required to operate the driving, traction, and steering systems, distance traveled, dust density, and acceleration at specific points on the train. These data were recorded on two 8-channel oscillographs, and were compared with 'base values' obtained during operation over a level paved road to determine the causeeffect relation of terrain factors on cross-country operation of the Overland Train. Effects of terrain on crosscountry operation were decrease in speed, increase in path length, and increase in fuel consumption. These effects were attributed to microgeometry features and the direction of travel across these features. Quantitative relations between speed and fuel consumption were established for the terrain types tested. Terrain types along the two courses traversed are compared to the terrain of world deserts of North Africa, the Middle East, and South Central Asia.
