A Team Leader prepares to move at night or under conditions of zero visibility. The move is split into a series of legs with RVs at obvious geographical features (P1, P2 and P3). At each of these points a compass bearing is taken to the next RV (x degrees). The reverse bearing is also taken (x -180 degrees), as the previous RV will serve as a rallying point if any of the soldiers becomes lost. The route avoids obvious danger areas and an E RV is chosen at the corner of the wood (E) in the event of the team being separated after a contact with the enemy. When the team reaches the marsh, the area is by-passed, a pace count enabling them to return to their original bearing on the other side. On the final leg to the deserted building on the other side of the stream, use is made of offset navigation: a deliberate deviation in the route is introduced to the east of the building. On reaching the other side of the stream, the team makes a 90 degree turn to move westerly along the bank until the outer fence is reached. Scouts then recce the final RV.
