1. The policies and procedure enunciated herein are published for the information and guidance of the Army and the Navy.

2. It is vital to success in war that the Army and the Navy so coordinate their action as to produce the most effective mutual support. To accomplish this, it is essential that both services have a common, definite understanding of their respective functions in national defense and of the approved methods for attaining coordination in operations.

3. The aim of this publication is to assemble in one volume all joint policies, agreements, or instructions which have been approved by the War and Navy Departments, with a view to securing effective coordination. It is divided into two parts:

PART I.--Policies to govern joint action of the Army and the Navy.

PART II.--Policies, agreements, and joint instructions which, by providing effective organization and agencies for coordination, and by enunciating standard practice, promote harmonious joint action.

4. The loose-leaf form is adopted, in order to facilitate revision and to permit the addition of new subject matter.

5. This publication supersedes "Joint Action of the Army and the Navy" published April 23, 1927, which is rescinded. The pamphlets entitled "joint Overseas Expeditions" and "Regulations, Maneuver Rules and Umpire Instructions for Joint Army and Navy Exercises" are incorporated in this publication as Chapters VI and VII, respectively, and their classification changed to "Confidential."
