1. INTRODUCTION

A list of common U.S. artillery terms and their British equivalents is presented below. It is felt that this list will be a considerable help to our artillery units since many of them may be in action beside British units, or in support of British units, or vice versa. The list of terms was compiled at a British artillery school.
