Psychology for the Armed Services intends to serve not only as a textbook at the college level but also as a volume in which the military and naval applications of psychological principles and the basic tenets themselves are most favourably developed. As far as a single standard work can be of influence, this book has proved significant in rooting a permanent realization in the armed services of the immense value of the subject. This is not simply a war book, it is a comprehensive work of broad and continuing military usefulness.
