Subj:  HANDLING INSTRUCTIONS FOR COMMUNICATIONS SECURITY MATERIAL
       SYSTEM (CMS)

Ref: (a) CMS 1 
     (b) CMS 5 
     (c) CMS 6

1.  This letter supplements instructions for the handling and
safeguarding of CMS material contained in the references. 

2.  As a person who is in a position to become a recipient of CMS
material, you will familiarize yourself with the applicable
provisions of the references and this letter.

3.  General

    a.  Normally, only those publications, devices, and equipment
which are either actually in use or which must be readily avail-
able, should be drawn from the CMS Custodian (ARAB).

    b.  Regularly superseded CMS material will be drawn on the
last working day preceding its effective date unless other
arrangements have been made with the CMS Custodian.  Superseded
material will be returned to the CMS Custodian no later than the
first working day of each month.

    c.  Per requirements established by reference (a), all keying
material marked crypto must be destroyed within 12 hours of
supersession.  When a user is not operational over a weekend or
holiday period, the destruction period may be extended up to a
maximum of 72 hours.  Destruction of all keying material will be
conducted by two properly cleared people.  Effective keying
material used during a normal workday may not be extended beyond
the 12 hours unless approved by the controlling authority.  As a
responsible user, you will destroy specifically designated
accountable legends 1 and 3 material within 12 hours after
termination of the effective cryptographic period.  Destruction
shall be in accordance with reference (a) par. 540E.  Placement
of superseded keying material in a burn bag does not constitute
destruction.  Complete destruction is defined as destruction by
burning, shredding or other authorized means to make reproduction

impossible.  A local destruction report will be submitted to the
CMS custodian in accordance with 784H of reference (a).  This
report shall be submitted no later than the second day of each
month following the effective cryptographic period.

    d.  All personnel having access to COMSEC keying material and
cryptographic maintenance manuals will be formally authorized by
the commanding officer.

    e.  You must be familiar with all publications held and know
all specific or unusual handling instructions.

4.  Special Instructions

    a.  The storage facilities for CMS material shall provide the
maximum protection from theft, compromise, loss, damage or
deterioration.  Proper protection will be provided against
unauthorized access (by those without proper clearance or a
"need-to-know").  Containers for storage of classified keying
material shall provide two person integrity (TPI) protection to
prevent any individual from obtaining lone access.

    b.  A running inventory will be maintained for strict control
of CMS material.

    c.  All publications shall be placed in their proper storage
space when not actually in use.

    d.  Combinations of containers used to store cryptographic
material shall be changed at least once every 6 months, or
whenever a person having knowledge of the combination is
transferred.  Information concerning the data of the last
combination change, and instructions pertaining to the procedures
to be followed if the safe is found opened, should be posted on
each safe.  Safe combinations for COMSEC material will be
forwarded to the Marine Corps Command Center for storage.

    e.  CMS material will not be removed from the Military
District of Washington without the permission of the Responsible
Officer.

    f.  CMS material including publications, devices, equipment
or parts thereof, may not be destroyed unless specifically
authorized by the CMS custodian.

    g.  Extracts may not be made from CMS material without
permission of the CMS custodian.

    h.  Any known or suspected compromise must be reported
immediately to the CMS custodian.

    i.  CMS material must be stored separately from other
material, regardless of classification.  In addition, effective,
superseded, and reserve onboard material must be separated from
each other.  Accessibility, security, and emergency action must
also be considered when separating this material.

    j.  Strict accountability and control of all CMS material
assigned to the watch or duty section must be maintained.  A 
watch-to-watch inventory must be conducted each time the watch
changes, or, each time the watch is assumed.  The oncoming watch
supervisor must inventory all keying material, cribs,
publications, and COMSEC equipment held.

    k.  Changes, corrections, or amendments to publications and
modifications to equipment must be made as follows:

        (1) All modifications to equipment must be made by
qualified technicians immediately and the residue returned to the 
CMS custodian.

        (2) All changes, corrections, and amendments must be made
immediately and all residue and superseded pages must be returned
to the CMS custodian for destruction.  The record of change in
each publication must be properly completed with the change,
correction or amendment entered, along with the date and the
signature of the two people who entered the change.  In addition,
two page checks will be made; one by the responsible user or an
alternate, and one by the person who entered the change.  Written
notice of the change entered and verification that the page
checks were completed will be submitted to the CMS custodian
along with the change residue.

    l.  The key cards should remain in the plastic wrapper until
they are needed.  After initial opening, the remainder of the
wrapper should not be removed from the key cards until they have
been superseded.

    m.  Page checks to "Qkits" are required whenever the "Qkit"
is opened, or at least monthly.  Qkits without locks will be page
checked daily.

    n.  A complete inventory will be conducted upon the occasion
of your relief from duty as the responsible user.  This inventory
will be coordinated with the CMS custodian.  The new responsible
user will sign for all CMS material charged to your section.

       (3) Sample CMS Responsibility Acknowledgment Form

1.  Purpose.  To ensure the proper distribution, control,
security, and accountability of communications security material
used throughout Headquarters Marine Corps, and to provide
cryptographic security for national security related information.

2.  Cancellation.  MCO 2670.l.

3.  Information

    a.  The communications security material system (CMS) is
designed to ensure that certain categories of highly sensitive
classified information and equipment are protected by providing
strict accountability throughout their existence.

    b.  CMS-distributed material is any publication or piece of
equipment that is accounted for within the CMS.

    c.  Operating Principles of CMS.  The operating principles of
CMS are based on the following safeguards:

        (1) A continuous chain of custody receipts by use of
transfer reports and local custody documents.

        (2) Positive accounting records, such as periodic
inventory reports, destruction records, transfer reports, and
local custody records.







MCO 2670.1A

        (3) The requirements for the immediate reporting of
COMSEC material insecurities and practices dangerous to security.

4.  Definitions

    a.  CMS Custodian.  A designated individual who is
responsible to the Commandant of the Marine Corps for all COMSEC
publications and equipment and the proper maintenance of all
applicable records.

    b.  CMS User.  A properly cleared and authorized individual
whose duties require COMSEC material in order to accomplish an
assigned duty.
   
    c.  Responsibilities.  CMS users, whether they personally
sign for COMSEC material on local custody or whether they use
COMSEC material signed for by someone else (e.g., a watch
supervisor), are responsible for the proper security, control,
accountability, and disposition/destruction of the material.  A
CMS user must, therefore, comply with applicable security,
control, and internal accountability procedures outlined in
reference (a), CMS instructions published by the command and
higher authority, and other related CMS administrative and
procedural publications.  CMS users must also comply with CMS
technical and managerial guidance and instructions issued by the
CMS account custodian (or local holder custodian, if applicable). 
CMS users may not receive COMSEC material from more than one CMS
account or local holder account.

    d.  Relationships.  CMS account commands may issue COMSEC
material to properly cleared and authorized user personnel who
have a need-to-know from within or outside the CMS account
command.  When a user relationship exists between a CMS account
command and a command or unit not under the jurisdiction of the
Commanding Officer of the CMS account command, a letter of
agreement is required in accordance with article 445 of reference
(a).  In the letter of agreement, the user command must agree to
abide by and adhere to the policy and procedures in CMS 1, CMS 6,
and CMS 5, and in the CMS instruction issued by the CMS account
command concerning proper security, control, accountability, and
destruction of the COMSEC material held by the user command.

    e.  Issuing COMSEC Material to Users.  All COMSEC material
issued to CMS users must be issued on local custody, using a CMS
17 card or a local SF 153 transfer report.  Article 769 of
reference (a) outlines the signature requirements for material
issued on local custody documents.

                                                    MCO 2670.1A
  
    f.  CMS Responsible Officer.  A flag or general officer in
command status, or any officer occupying the billet of a flag or
general officer with command status may either assume personal
responsibility for routine CMS matters or may designate a senior
staff officer to be responsible for routine CMS matters.  
Commanders not meeting the above requirement may not designate a
CMS Responsible Officer.

    g.  Duties and Responsibilities of a CMS Witness.  The CMS
witness is required to be familiar with the applicable procedures
contained in reference (a) and in related administrative
publications, as well as in command directives.  An individual
who witnesses a CMS inventory or destruction or any other CMS
report or local CMS record is equally responsible for the
following:

        (1) The accuracy of the information listed on the report
or record.

        (2) The physical sighting of all material inventoried or,
if applicable, the appropriate local custody issue records when
sighting a CMS 16-1 or SF 153 inventory report.

        (3) The physical sighting of all material to be destroyed
and the actual destruction of the material.  If witnessing a CMS
2-1 or SF 153 destruction report, the witness is responsible for
also verifying any local destruction records used to document
entries on the CMS 2-1 or SF 153.

        (4) The timeliness and validity of the report or record.

5.  Dissemination of Information

    a.  The dissemination of information from COMSEC
publication(s) shall be limited to those persons whose official
duties require access to this information.

    b.  COMSEC material will be issued only to personnel who have
been granted receipting authority by CMC or his Responsible
Officer (RO).  Requests for access are to be submitted by user
letter as shown in enclosure (1).  This list of authorized
personnel will be kept current by the CMS user and on file with
the CMS custodian.

    c.  It is the duty of all persons having knowledge of any
possible discrepancies, loss, compromise, or unauthorized viewing
of COMSEC publication(s) or equipment to report such knowledge to
the CMS custodian immediately.



                                3
MCO 2670.1A

6.  Custodian/Alternate Custodian Responsibilities

    a.  The CMS custodian or alternate custodian(s) is respon-
sible to the Responsible Officer, Director of Administration and
Resource Management (DirAR) for the proper management of
Headquarters Marine Corps COMSEC material and is that RO's
primary advisor concerning the physical security and handling of

local holder custodian's duties.

        (3) To periodically conduct training in CMS procedures
and to provide guidance to staff agency personnel who use COMSEC
material.

security for the COMSEC material held by the account.

        (7) To issue COMSEC material on local custody to
authorized persons.

        (8) To provide written guidance to personnel to whom
material is issued on local custody.  The guidance must be
specific information concerning the proper handling,
safeguarding, and destruction/disposition of the material issued.

Ref: (a)  CMS 1 
     (b)  CMS 5 
     (c)  CMS 6

1.  This letter supplements instructions for the handling and
safeguarding of CMS material contained in the references. 

2.  As a person who is in a position to become a recipient of CMS
material, you will familiarize yourself with the applicable
provisions of the references and this letter.

3.  General

    a.  Normally, only those publications, devices, and equipment
which are either actually in use or which must be readily avail-
able, should be drawn from the CMS Custodian (ARAB).

    b.  Regularly superseded CMS material will be drawn on the
last working day preceding its effective date unless other
arrangements have been made with the CMS Custodian.  Superseded
material will be returned to the CMS Custodian no later than the
first working day of each month.

    c.  Per requirements established by reference (a), all keying
material marked crypto must be destroyed within 12 hours of
supersession.  When a user is not operational over a weekend or
holiday period, the destruction period may be extended up to a
maximum of 72 hours.  Destruction of all keying material will be
conducted by two properly cleared people.  Effective keying
material used during a normal workday may not be extended beyond
the 12 hours unless approved by the controlling authority.  As a
responsible user, you will destroy specifically designated
accountable legends 1 and 3 material within 12 hours after
termination of the effective cryptographic period.  Destruction
shall be in accordance with reference (a) par. 540E.  Placement
of superseded keying material in a burn bag does not constitute
destruction.  Complete destruction is defined as destruction by
burning, shredding or other authorized means to make reproduction

impossible.  A local destruction report will be submitted to the
CMS custodian in accordance with 784H of reference (a).  This
report shall be submitted no later than the second day of each
month following the effective cryptographic period.

    d.  All personnel having access to COMSEC keying material and
cryptographic maintenance manuals will be formally authorized by
the commanding officer.

    e.  You must be familiar with all publications held and know
all specific or unusual handling instructions.

4.  Special Instructions

    a.  The storage facilities for CMS material shall provide the
maximum protection from theft, compromise, loss, damage or
deterioration.  Proper protection will be provided against
unauthorized access (by those without proper clearance or a
"need-to-know").  Containers for storage of classified keying
material shall provide two person integrity (TPI) protection to
prevent any individual from obtaining lone access.

    b.  A running inventory will be maintained for strict control
of CMS material.

    c.  All publications shall be placed in their proper storage
space when not actually in use.

    d.  Combinations of containers used to store cryptographic
material shall be changed at least once every 6 months, or
whenever a person having knowledge of the combination is
transferred.  Information concerning the data of the last
combination change, and instructions pertaining to the procedures
to be followed if the safe is found opened, should be posted on
each safe.  Safe combinations for COMSEC material will be
forwarded to the MCCC for storage.

    e.  CMS material will not be removed from the Military
District of Washington without the permission of the Responsible
Officer.

    f.  CMS material including publications, devices, equipment
or parts thereof, may not be destroyed unless specifically
authorized by the CMS custodian.

    g.  Extracts may not be made from CMS material without
permission of the CMS custodian.

    h.  Any known or suspected compromise must be reported
immediately to the CMS custodian.

    i.  CMS material must be stored separately from other
material, regardless of classification.  In addition, effective,
superseded, and reserve onboard material must be separated from
each other.  Accessibility, security, and emergency action must
also be considered when separating this material.

    j.  Strict accountability and control of all CMS material
assigned to the watch or duty section must be maintained.  A 
watch-to-watch inventory must be conducted each time the watch
changes, or, each time the watch is assumed.  The oncoming watch
supervisor must inventory all keying material, cribs,
publications, and COMSEC equipment held.

    k.  Changes, corrections, or amendments to publications and
modifications to equipment must be made as follows:

        (1) All modifications to equipment must be made by
qualified technicians immediately and the residue returned to the 
CMS custodian.

        (2) All changes, corrections, and amendments must be made
immediately and all residue and superseded pages must be returned
to the CMS custodian for destruction.  The record of change in
each publication must be properly completed with the change,
correction or amendment entered, along with the date and the
signature of the two people who entered the change.  In addition,
two page checks will be made; one by the responsible user or an
alternate, and one by the person who entered the change.  Written
notice of the change entered and verification that the page
checks were completed will be submitted to the CMS custodian
along with the change residue.

    l.  The key cards should remain in the plastic wrapper until
they are needed.  After initial opening, the remainder of the
wrapper should not be removed from the key cards until they have
been superseded.

    m.  Page checks to "Qkits" are required whenever the "Qkit"
is opened, or at least monthly.  Qkits without locks will be page
checked daily.

    n.  A complete inventory will be conducted upon the occasion
of your relief from duty as the responsible user.  This inventory
will be coordinated with the CMS custodian.  The new responsible
user will sign for all CMS material charged to your section.
