Field Artillery Fire Control NCO
June 1945 is the manual's publication date; no calendar effective date is stated for this suggested reclassification.
- The double-asterisk recommendation of 645 applies to Field Artillery Fire Control NCO. The single-asterisk recommendations of 594, 596 and 645 apply to the separate Instrument Sergeant title from AR 615-26, September 1942 and supplements.
- No June 1945 title is listed for SSN 577, so retaining the number does not establish continuation under the same title.
