Australian Guerilla series
The Australian Guerilla series was a series of 6 handbooks published in World War II by Ion Idriess. Idriess had been a sniper during World War I. The books were written when Australia was under threat of invasion during World War II. This book is written in the author's own inimitable, man-to-man style. Mr. Idriess here reveals the secrets of the dead shot. What to do and what not to do, are impressed upon the budding rifleman. He brings out clearly the importance of apparently trifling points. No more opportune book could have been  published. Australia — for the first time in its history — has been bombed. Invasion now looms on our northern frontier. The imperative need now is for rifles—and more rifles. Here is a book that should be in the hands of every able-bodied – Australian. 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 Books in the series. 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.
