Strength And Composition

Subject to variation according to the situation, one twentieth to one

third of a command may be assumed as a suitable strength for the advance

guard. The larger the force, the larger in proportion is the advance

guard, for a large command takes relatively longer to prepare for action

than a small one. In large commands it is usually composed of all arms,

the proportions depending on the nature of the work, character of the

country, etc.
