The books were written when Australia was under threat of invasion during World War II.

[2] This book is written in the author's own inimitable, man-to-man style.

Mr. Idriess here reveals the secrets of the dead shot.

The motives that have lnspired the writing of it are— the author says— twofold: 'The consciousness that hundreds of thousands of Australians have not even a rudimentary knowledge of how to effectively use and care for the Service Rifle; and the conviction— gathered from forty years' experience— that this handicap can be largely overcome by studying and grasping a few fundamental principles.'

These principles are clearly and explicitly laid down, and- abundantly illustrated, in this manual.
