"How U.S. Artillery Terms Differ from British" from Intelligence Bulletin, December 1943

[Intelligence Bulletin Cover]  
The following comparison of British and U.S. artillery terminology was originally printed in the December 1943 issue of the Intelligence Bulletin.

[DISCLAIMER: The following text is taken from the U.S. War Department Intelligence Bulletin publication. As with all wartime intelligence information, data may be incomplete or inaccurate. No attempt has been made to update or correct the text. Any views or opinions expressed do not necessarily represent those of the website.]



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.
