The discipline of military psychology involves the systematic and scientific study of the selection, training, adaptation, and performance of soldiers. Military psychology, by necessity, is a heterogeneous field of inquiry. On the one hand, it draws on all subdisciplines of psychology to understand the variables that affect soldier performance while on the other hand, lessons learned from military psychology are of vital importance to all areas of psychology.

The purpose of this collection of readings is to capture significant developments from military psychology that are of general interest and importance to all psychologists and to promote understanding in human behaviour in challenging contexts.

Volume One: Selection, Training and Performance captures significant advances in how soldiers are selected, assigned, and trained.

Volume Two: Applied Experimental and Engineering Psychology includes topics of human factors engineering, cognitive engineering, ergonomics, situational awareness and soldier performance.

Volume Three: Stress and Resilience focuses on classic and contemporary studies of combat stress and its consequences.

Volume Four: Leadership, Culture and Morale advances the understanding of leading people in the contexts of dangerous environments.
