5. Engineer activity. Engineer equipment other than river-crossing equipment resembles
civilian engineer equipment; it can be identified on air photos by shape, shadow, and the
surroundings in which it is located. River-crossing equipment is difficult to conceal and
easy to identify by its characteristic size and shape (Figure 2-5). An armored-launched
vehicle bridge (ALVB) is depicted at Annotation A.
