This code book, to be known as "Field Code No, 1", is issued to division, brigade, regimental and battalion head- quarters of your division. Whether or not it is issued to neighboring divisions must be determined by you before you send them telegrams encoded by its use. (See G. O. No. 172, G. H. Q. American E. F., 1918.) 2. IN CASE OF LOSS OF THIS BOOK, NOTIFY SUPERIOR AUTHORITY AT ONCE. BURN IF IN DANGER OF CAPTURE. 3. Coded messages sent by telephone will be preceded by "FC1". If transmission is difficult, use the following telephone alphabet, authorized by G. O. No. 103, 1918: A—Able N—Nan B—Boy O—Opal C—Cast P—Pup D—Dock Q—Quack E—Easv R—Rush F—Fox S—Sail G—George T—Tare H—Have U—Unit I —Item V—Vice J—Jig \V—Watch K—King X—X-ray • L—Love Y—Yoke M—Mike Z—Zed Example: If the operator receives "buy" as "vie," and difficulty is experienced in distinguishing "B" from "V," "buy" "may be spelled "boy-u-3r ." 4. Coded messages sent by telegraph or radio will be pre- ceded by the group "FC1." 5. The use of this code for regular routine reports should be limited to actual necessities. Such reports should be trans- mitted by other means than radio or earth-telegraphy. 6. Avoid use of words not in code book when other word> with same significance are provided. Words spelled out, letter by letter, not only take time to code, transmit and decode, but they are one of the favorite points of attack by enemy code men. 7. Where two or more code groups are assigned the same letter, syllabic, word or phrase, first one and then another should be used so that in a series of messages each occurs about tne same number of times. In particular, no group should ever appear twice in the same message. 8. At least one group marketj "Null" should be used for every ten code groups in a message. These should be placed at irregular intervals. A "Null" should always occur between double letters; thus, the word "boot" would be encoded: (bi (o) (Null) (o) (t) AWK CUF NAW PCU JAK Note that different groups are used for letter "0." 9. In messages sent by radio or earth-telegraphy, addresses will be used only when context of message does not indicate for whom intended. When used, they must be in code. 10. Signatures must be in code if message is sent by radio or earth-telegraphy. Usually it will be sufficient to indicate origin by some word in code book previously agreed upon by each commander and his immediate subordinates. 11. The message handed Signal Corps operator should bi- in the following form on any suitable paper: "No. 1. 15:40 FC1 AWK CUF NAW PCU JAK Send this message to First Division. J. M. Capt., 1st Infantry." 12. Items should always appear in the following order: (a) Number of message. (b) Hour of signature. (c) Group designating code used. (d) Body of message. ('e) Order directing transmission. Order directing transmission may also indicate means to be employed when deemed necessary by the commanding officer, but this will, in general, be left to the discretion of the Signal Corps. 13. Blank spaces at end of book are for use of divisions for designation of organizations and local geographical points, or for such other use as may be desired. Words assigned will be reported to Corps, Army and General Headquarters, and to neighboring divisions 14. Bead G. O. No. 103, G. H. Q. American E. F., 1918, before using this code. 15. For the convenience of officers having occasion to use it the "Emergency Code List," which has been issued to companies, is published in the front of this book.
