e. Penetrate obstacles as follows: (1) Enter deep ditches feet first to avoid injury. (2) Go around chain-link and wire fences. Go under fence if unavoidable, crossing at damaged areas. DO NOT touch fence; look for electrical insulators or security devices. (3) Penetrate rail fences, passing under or between lower rails. If impractical, go over the top, presenting as low a silhouette as possible (Figure 1-4). (4) Cross roads after observation from concealment to determine enemy activity. Cross at points offering concealment such as bushes, shadows, bend in road, etc. Cross in a manner leaving your footprints parallel (cross step sideways) to the road. (Figure 1-5). (5) Use same method of observation for railroad tracks that was used for roads. Next, align body parallel to tracks with face down, cross tracks using a semi-pushup motion. Repeat for the second track. (Figure 1-6).
