With the exception of places with deep sand and rugged valleys, the desert in the combat zone of the German troops was, in general, passable for both wheeled and tracklaying vehicles. The influence of terrain on tactical operations is just as decisive in the desert as in other theaters of war. It is more difficult, however, to take advantage of the peculiarities of the terrain for one's intentions, since due to the lack of forests, cultivated areas, villages, etc., it is seldom possible for troops to approach and assemble under cover. Nonetheless, even in the desert, there are widely different opportunities to take advantage of the terrain. For example, troop assemblies can be concealed in ravines and valleys from ground observation and-to a limited extent-even from air observation.
In both attack and defense, the important thing was always to have reconnoitred the terrain carefully in advance. In attack, importance was attached to choosing ground that could be easily traversed by motor vehicles and, especially, which offered a covered approach, at least in part, through the utilization of terrain contours. The fact that the desert surface was easily traversed by motor vehicles made it easy to advance in light formations with few casualties, as well as to make all kinds of enveloping movements. In actual practice, few limitations existed on freedom of movement. Thus, it was also easily possible to shift the direction of an attack. During an attack, the tank battle always occupied the foreground. Attempts were made to compensate for the lack of good observation posts by sending out forward observers. Difficulties arose for attackers if they were compelled to use the southern portion of the desert proper, which in places was covered with soft soil.
