The demands on the fighting-efficiency of this arm--as is partly expressed in the regulations--may be summed up as follows: all preconceived ideas and theories as to its employment must be put on one side, and its one guiding principle must be to support the cavalry or infantry at the decisive point. This principle is universally acknowledged in theory, but it ought to be more enforced in practice. The artillery, therefore, must try more than ever to bring their tactical duties into the foreground and to make their special technical requirements subservient to this idea. The ever-recurring tendency to fight chiefly the enemy's artillery must be emphatically checked. On the defensive it will, of course, often be necessary to engage the attacking artillery, if there is any prospect of success, since this is the most dreaded enemy of the infantry on the defensive; but, on the attack, its chief duty always is to fire upon the enemy's infantry, where possible, from masked positions. The principle of keeping the artillery divisions close together on the battlefield and combining the fire in one direction, must not be carried to an extreme. The artillery certainly must be employed on a large plan, and the chief in command must see that there is a concentration of effort at the decisive points; but in particular cases, and among the varying incidents of a battle, this idea will be carried out less effectively by uniformity of orders than by explaining the general scheme to the subordinate officers, and leaving to them the duty of carrying it out. Accordingly, it is important that the personal initiative of the subordinate officer should be recognized more fully than before; for in a crisis such independent action is indispensable. The great extent of the battlefields and the natural endeavour to select wooded and irregular ground for the attack will often force the artillery to advance in groups or in lines one behind the other, and to attempt, notwithstanding, united action against the tactically most important objective. This result is hard to attain by a centralization of command, and is best realized by the independent action of tactically trained subordinates. This is not the place to enter into technical details, and I will only mention some points which appear especially important. The Bz shell _(Granatschuss)_ should be withdrawn as unsuitable, and its use should not form part of the training. It requires, in order to attain its specific effect against rifle-pits, such accurate aiming as is very seldom possible in actual warfare.
