On the march the first halt is for 15 minutes taken after 45 minutes of marching. The men should be taught to use this time to adjust their clothing and equipment, and answer the calls of nature. Do not halt where there are houses, etc., on this first halt, as a great many men want to relieve themselves. The succeeding halts are for 10 minutes after 50 minutes of marching--except of course during a forced march--when you would march for a longer period. During rainy or very hot weather the halts should be made oftener. Do not have any straggling, remember if a man falls out he must have a certificate signed by an officer stating the cause. Have one officer march in rear of the company. Be careful about the use of water. Have your men take a good drink early in the morning just after reveille, and on the march use their canteen sparingly. One canteen of water must last one man one day. Do not allow men to drink until after the second halt. On reaching camp the kitchens are put up, latrines are dug, and tents are pitched. When everything has been tended to each man should give his feet a good salt water bath. Put them in the water and let them remain there for 2 minutes. Do not dry them by rubbing, but sponge them--this will harden the feet. This should be done for the first three days, after which it can be dispensed with. A change of socks daily should be made, take one pair of socks from the pack, and wash out the dirty pair. Try to avoid night marching. The leading company in each regiment regulates the rate of march. "The marching efficiency of an organization is judged by the amount of straggling and elongation and the condition of the men at the end of the march." (i.d.r., 632.) Remember a sanitary squad should be detailed daily to police the immediate vicinity after each halt. Field Work. Field work will be classified under the following heads: Orders, Deployment, Fire, Attack, Defense, Leadership, Communications, Night Operations, Patrols, Advance Guards, Rear Guards, Flank Guards, Camp, March Outpost, and Outpost. (a) AN ORDER is the will of the commander expressed verbally or in writing to his subordinates. It should be clear, concise and to the point. A field order should be given as follows: 1. Information of the enemy and supporting troops. 2. General plan of the commander. 3. Dispositions of the troops. 4. Instructions for the trains. 5. Place where messages are to be sent. (b) DO NOT DEPLOY too early. It is very fatiguing, and has a tendency to disorganize the skirmish line. The major designates the companies to be on the firing line, and those to remain in support. The distance between the firing line and support is from 50 to 500 yards. The support should be as close as possible under cover.
