3. Infantry mounted officers are apt to forget that their horses are given to them in order to give them more mobility. There are many occasions on which, by cantering on and making arrangements previous to the arrival of the unit which they command, they can save a great deal of valuable time and often much marching and counter-marching. 4. Never allow the pace in front to be hurried on a march. It is much easier to march at the head than at the rear of a column. 5. Before opening fire, carefully consider the situation. If you feel certain of being able to deal with the enemy, let him approach close before disclosing yourself, and then destroy him. If, on the contrary, he is so much superior to you that you cannot hope to be able to do this, you should open at a long range, but in these circumstances do not hurry the rate of fire to begin with. It takes an exceptional man to fire more than 200 rounds in a short space of time without being shaken. 6. It is a sound rule always to pursue the line of action which your opponent does not wish you to pursue. If, for instance, in the circumstances mentioned in the above paragraph the enemy open fire on you at a long range, you may presume that he does so in order to keep you at arm’s length, and if you halt you are probably doing what he wishes you to do. 7. However small your party may be when acting independently, it is responsible for its own protection, and it should always have an advance guard or its equivalent. 8. Whenever you have an opportunity of doing so, and the tactical situation allows of it, check your ranges by firing at an auxiliary mark where you can see the splash of your bullet, such as a dusty road or water. 9. When you have ascertained the correct distances of the object, make a range-card and pass on your information to neighbouring troops. 10. If you see a good opportunity of inflicting loss on the enemy, but it is impracticable to check the range, use combined sights. 11. Remember that if the target you are shooting at is large enough and you know the range, you can inflict heavy losses with rifle and machine-gun fire at ranges well over 2,000 yards. 12. Do not forget to make use of the map when estimating a range. 13. Although the secret of success in an engagement is the proper co-operation of the different arms of the service, the platoon commander must not cry out for artillery assistance when he has the means of carrying out his task in his own platoon, which, with its riflemen, its Lewis gunners, its bombers, and its rifle bombers, is, in itself, a miniature division. In an action where telephonic communication has broken down this rule applies with special force.
