' ;··#{' '-~\ ~- REF ID:A66161 A fJREET/NfJ FROM The Chief The resumption of publication of the Army Security Agency Review affords a most welcome opportunity for me to extend greetings to each individual member of the Agency and to share with you the benefits gained by closer association in our common interests. When the review first appeared three years ago, the initial response through the Agency was most enthusiastic, and it was with regret that circumstances beyond our control forced us to discontinue its publication. The purpose of the ASA Review remains the same as before: to provide the Army Security Agency with a semi-technical bi monthly publication for articles on the sub ject matter of the work and activities of the Agency insofar as the classification CON FIDENTIAL wlll permit. As Chief, Army Security Agency, I am interested primarily in two obj e ct iv e s: maintaining excellent morale and improving the high technical standards which the Agency has achieved. Morale is a most important factor in all military and techni cal services, and only through improving our technical skills can we enhance the quality and value of our work. General Bradley once said, "Good ideas must not be kept secret; let's share them." By putting our ideas together through the medium of the ASA Review, by learning something of the way and manner in which we live, work, and play in the various installations, a further contri bution can be made toward the future success of the Agency by the publication of the ASA Review -- our own service journal.
