A little practice should be held by the regiment as a whole in forming outpost; one with the regiment as the outpost and one with the regiment as the whole command, one battalion forming the advance guard on the march. In the latter, a halt order should be issued and outpost formed from the advance guard battalion; when completed a march order should be issued by which the new advance guard passes through the outpost line. The outpost should then be assembled and take its place in column. We do this very easily in map problems; try it on the ground, especially in rather close country. [Sidenote: Mounted scouts] The mounted scouts. While the mounted scouts have been taken from the infantry regiment there is still with each regiment a mounted detachment of orderlies. A few mounted scouts well trained are invaluable to an infantry regiment when operating alone. The commander of an infantry regiment, if wise, will see that these orderlies are trained as scouts and then when necessary he can so use them. Their most important and frequent use will be as the mounted point and flank patrols for an advance or rear guard and for patrolling to the front of an outpost line. To be of any value they must be well instructed in these duties as described under advance guard. Being mounted they are much more valuable than a dismounted patrol for gaining information from the flanks and getting it back to the commander in time to be of some use. These orderlies can be trained in this work without interfering materially with their instruction in the care of horses and equipment and it can be given along with instruction in horsemanship. VII MARCHING Ability to march under war conditions is of primary importance in the training of infantry. There is much more marching than fighting in war and, no matter how well a man may be trained otherwise, if he is unable to reach the field of battle he is of no value as a fighting man. [Sidenote: Requisites for marching] That the infantry soldier may be able to meet the requirements in this respect he must possess the necessary health and strength he must be properly shod, know how to care for himself on the march, especially how to take care of his feet, and his muscles must be properly developed. It is also necessary that the responsible officers know how to conduct the march and to care for the men. That the man has been allowed to enlist presumes the possession of the necessary health and strength and gives us a man who can be trained to meet all necessary requirements except when temporarily sick or disabled.
