The essential lessons taught to the SAS and all the world's top Special Forces units are shown in this series of illustrations:

A). Contour hills at a point two-thirds up the slope. This avoids paths and tracks in the valleys and prevents the team from silhouetted on the tops.

B). Use available cover (e.g. walk along the hedgerows rather than across an open field).

C). Avoid tracks if possible. If a highway serves as an essential landmark it can be followed some distance away (handrailing).

D). Use dead ground such as gullies and stream beds.

E). Night movement is slow but safer.

F). Cross open ground at the narrowest point.
