A collection of talks by an army officer explains and defends the soldier’s peacetime duties, correcting civilian misunderstandings and prejudice. The author argues that military training and organization serve to prevent war, support the general welfare, and fulfill constitutional obligations of common defense. He describes soldiers’ contributions to public works, disaster relief, recruiting and training, and the dangers of late mobilization, using practical anecdotes and analogies to show how preparedness reduces casualties and expense. The overall aim is to foster informed public appreciation for the military’s administrative and civic roles.
