Upon immediate reenlistment, reproduce the Chronological Record
page(s) containing entries subsequent to the last enlistment and
forward the copy(ies) with the original of the enlistment/
reenlistment document as directed in table 4-2, column B. Use
all upper case typeface when making entries. The use of
abbreviations and/or acronyms is encouraged.
2. Unit/Organization. Record name of the organization, to
include battalion which the Marine is assigned for primary duty
and the reporting unit code (RUC) and monitored command code
(MCC) for the Regular establishment. SMCR units will include the
RUC of the Reserve unit and not that of the Inspector-Instructor
staff. Record unit/organization entries with all lines starting
at the left margin or the first line starting at the left margin
and second and subsequent lines indented one space. For example:
2DBN 6THMAR 2DMARDIV HQCO 23DMAR 4THMARDIV
FMF CAMLEJ NC FMF USMCR SAN BRUNO CA
RUC 12220 MCC V26 RUC 141O1
3. Upon redesignation of an organization, record new
organization title, address, RUC, MCC, effective date, and
authority. No other entries are required in the primary duty and
remarks columns. For example:
VMGR-2
SANTA SANTA ANA
EL TORO CA MCC G37
RUC 02003 MCC 023
EFF DATE: 905150
AUTH: Co, MCCDC MSG 140814Z APR97
4. Primary Duty. The primary duty will reflect the abbreviated
descriptive title of only the primary duty and billet military
occupational specialty (BMOS). For Marines attending recruit
training and MCT use the BMOS 9900, and for Marines attending a
formal school use the intended military occupational specialty
(IMOS) as the primary duty. See MCO P1080.40, MCTFSPRIM. During
periods of nonduty such as confinement, unauthorized absence, and
in hands of civil authorities, the BMOS or IMOS is omitted. The
omission is supported by the remarks entry reflecting the nonduty
status. For Marines joined to the IRR, omit the BMOS.
