This section of two guns is therefore the smallest tactical unit, and the officer in command is solely responsible for the training and efficiency of his section. It is therefore absolutely essential that the machine-gun section commander should be a subaltern of not less than three years' service, specially selected for his keenness, efficiency, and self-reliance, who has passed the examination "C" for promotion, and who holds the special machine-gun certificate from a School of Musketry. A "destroyer" in the Royal Navy is commanded by a very junior officer, but he is most carefully selected for similar qualities to those mentioned, and is in addition required to possess the necessary professional qualifications—consequently it is a command much sought after, and competition enables the authorities to appoint the pick of the service and thus obtain the maximum efficiency where efficiency is the essence of successful employment in war. The best and nothing but the best is necessary to the successful employment of machine guns, and the importance of obtaining the very best officers as section commanders is so great that there is reason to doubt the utility of having machine guns at all if they are not commanded and handled by those who are in every way expert in their use.
In order to enable machine-gun sections to be trained in tactics and to co-operate with larger units in war, it is essential that they should be trained under a senior officer during peace.
