Illustrations

The book contains simple illustrations with vivid colours detailing in pictures what the wording of each section instructs a soldier to do in various situations. For example: in chapter one instructions are provided on the method and wording to be used when challenging movement of persons approaching the sentry position. The manual instructs the sentry to call out, "Halt, who goes there? Advance one and be recognised." When approached in response to this command the sentry is instructed to use the "challenge" part of the password and to expect the correct reply before allowing any further movement of the person(s) approaching his position. The password will have previously been set by the officers in command and have been made known to every soldier within the formation. It will take the form of two simple words, for example: the challenge part could be "sausages" and the reply "chips". Therefore, the sentry calls out "sausages" and expects the reply "chips". If the correct reply is not received the sentry would be expected to open fire on the enemy approaching as anyone without the password is to be treated as an enemy. The illustration to the right shows in words and pictures how a sentry should perform his duties in the event of requiring to challenge a person or persons who approach him.
