The platoon commander would then take each scheme in turn, visit with the whole platoon each position selected for the sentry, and decide finally what it would be best to do, giving, as usual, his reasons.

Having decided upon the positions of the sentries, and their line of retreat, so as not to mask the fire of the outguard, the next matter to consider would be the number of patrols that are required, and the particular areas of ground that must be examined by them periodically. The necessary trenches, obstacles, etc., would then be constructed.

Finally, the whole company should be assembled, marched to the position chosen for each outguard and the reasons for selecting the position explained by the company commander. The company should then be told off as an outpost company, and divided into outguards, supports, if any, and the necessary sentries over arms, patrols, etc., and marched to their respective posts.

If there is still time available each platoon commander can reconnoiter the ground for suitable positions for his outguards by night, take the outguards there, explain why the change of position is desirable, and direct the outguard commanders with their outguards to select positions for the sentries, following the same procedure as by day.

Although it is quite correct to select positions for night outposts during daylight, when possible, they should never be definitely occupied by the company before dark, when the forward movement could not be observed by the enemy. To practice night outposts by day is bad instruction, outguards and sentries are placed in positions which appear ridiculous to the ordinary mind, and the men get confused ideas on the subject. When it is desired to practice day and night outposts as an advanced exercise it is advisable to commence work in the afternoon, establish the day outposts, reconnoiter for the night outposts, make the change after dark and construct the necessary trenches, obstacles, etc., after dark.

It is, however, extremely important that the patrols should get to know their way about the country in front during the daylight, when possible, so that they will have some practice in recognizing land marks by night.

It frequently occurs, when training the company in outpost duties, that periods elapse during which the outguards are doing nothing. These opportunities should be taken to instruct the men in their duties when ordered to patrol to the front, the same system of demonstration being employed. For instance, the officer or noncommissioned officer commanding a piquet can select three men, point out certain ground in front which the sentries cannot see and which must be examined by a patrol, and proceed to instruct the whole picket in the best manner of carrying out this work. We will suppose that the patrol is working by day and that the ground to be visited is behind a small hill some 500 yards in front of the sentry. The commander of the picket will then explain to the men that the first object of the patrol is to reach the ground to be examined without being seen by any hostile patrols which may be moving about in front. Before proceeding further it is necessary for the patrol to decide upon the best line of advance. The various lines of advance will be discussed and the patrol asked to decide which they would select. Three other men can then be asked to give their opinion, and so on until all the men of the picket have expressed their views. The commander of the picket will then state which he considers the best line and give his reasons.

The next matter to decide is the method of advance to be adopted by the patrol. Are the three men to march past the sentry in one body and walk straight over the hill in front? If they do this there may be a hostile patrol hiding just behind the crest, watching the movements of our patrol, and directly the latter reach the hill they will be covered by the rifles of the hostile patrol at a few yards' range and will be captured or shot.

If the patrol is not to advance in one body how is it to act? There is plenty of time available, so that there are no objections to deliberate methods. The patrol should advance from cover to cover with one man always going forward protected by the rifles of the remaining two men who have halted in a good position to fire on any enemy that can fire on the leading man. The leading man having readied the cover in front will signal back all clear, and the two men in the rear will join him. They will then make their next advance in a similar manner.

By looking at the hill the patrol can make a good guess at the locality which a hostile patrol would select if it was on the hill. It would be a place where it could get a good view towards our outpost line, and where the patrol could not be seen itself from the outpost line. If the hill was quite bare with nothing but grass on it and flat round top, the best place for the enemy's patrol would be exactly on the top just behind the crest. In such a position he could not be seen by any sentry to the right or left of our picket. For example, if the hostile patrol chose a place on the side of the bare slope of the hill and looked over the crest line it would not be seen by our sentry, but it might be seen by another one on the flank.
