GENTEX/REMARKS/1. This is a HQMC PP&O (POP/POR/POF), HQMC I&L
(LPM/LPO/LPS), TECOM (MAGTF TC G-3, policy and standards division),
MCICOM (G-3/5), MARFOR readiness and exercise offices, and MEF
readiness and exercise offices coordinated message.
2. Purpose. This MARADMIN provides interim guidance for CBRND
readiness reporting specific to training, equipping, and assessment
/certification in accordance with references (a) through (e). This
MARADMIN cancels MARADMIN 141/25.
3. Background. The Marine Corps organizes, trains, equips, and
certifies forces through exercise-based scenarios to ensure the
operating forces can operate, survive, and accomplish assigned
missions in Chemical, Biological, Radiological, and Nuclear (CBRN)
environments. This approach enables forces to execute required
Mission Essential Tasks (METs) in support of Combatant Commanders
and designated Joint Force Commanders when facing a CBRN threat or
hazard.
4. CBRND training and equipment factors. CBRND readiness is
evaluated across three factors, as outlined in paragraphs 4.a.
through 4.d. Commanders will assess and assign their units' CBRND
Training Levels (T-level), Supply Levels (S-level), and overall
CBRND Level using these factors, and applicable reason codes
resident in the Defense Readiness Reporting System - Strategic
(DRRS-S) that identify limiting factors. When the overall CBRND
Level is below Level 1, commanders will forecast an improvement date
and briefly describe the actions required to achieve an overall
Level 1 or explain why such a date cannot be determined.
4.a. Factor-1: CBRND individual and team training.
4.a.1. Individual and initial team training requirements.
Service-level individual training requirements include the CBRND
Individual Training Standards (ITS), the CBRND Individual Protective
Equipment Confidence Exercise (IPECE), and initial team training, as
outlined in reference (b) and (d), and are reported in the Marine
Corps Training Information Management System (MCTIMS) as CBRND
annual training and initial CBRN Defense Team training. Individuals
and teams are only required to complete Marine Common Skills (MCS)
or performance steps that are supported by the unit Table of
Equipment (T/E).
4.a.2. CBRND Team designation. Commanders will conduct analysis to
assess the requirement for CBRND Teams based on the threat and
available resources, in accordance with the T/E. These teams will
be tailored to mission requirements and scalable to meet the demands
of the evolving operational environment and threat conditions,
thereby enabling more efficient resource allocation and
prioritization of training toward increasingly refined mission sets.
Where practical, MEF and MSC commanders should codify team
requirements in the appropriate standing operating procedures.
4.a.3. MCTIMS is the sole authoritative data system for tracking,
recording, evaluating, and reporting individual and collective
service-level CBRND training requirements. In accordance with
reference (a), this includes all unit-level prescribed individual
and team CBRND training requirements.
4.a.4. Reporting. Units shall report only the overall CBRND
training status percentage generated by MCTIMS in DRRS-S. This
percentage is the sole authoritative, real-time assessment of unit
compliance with all service-level CBRND individual and team
training requirements and shall be used for readiness assessments
and inspection purposes.
4.b. Factor-2: Mission Essential Tasks (METs) evaluated under CBRN
conditions.
4.b.1. Go-level commands will assess their subordinate commands'
Mission Essential Task Lists (METLS) to identify and publish an
authoritative list of METs for training and evaluation under CBRN
conditions. Commands will report METS designated for execution
under CBRN conditions as Factor-2 data in DRRS-S. During
service-level METL reviews, services will incorporate these specific
METS as mandatory for execution under CBRN conditions.
4.b.2. Reporting. In accordance with reference (c), commanders
will provide a subjective assessment of their units' readiness to
accomplish applicable METs under CBRN conditions, excluding any METs
waived as discussed in paragraph 4.b.1.
4.c. Determining CBRND T-level:
4.c.1. T-1: the unit has satisfied the criteria for T-3 and has
completed an evaluated exercise under CBRN threat conditions (e.g.,
Marine Corps Combat Readiness Evaluation, Service Level Training
Exercise, Certification Exercise, or an externally evaluated event)
within the previous 12 months or the current deployment cycle.
Commanders will not report a T-1 rating unless the unit has been
formally evaluated during such an exercise or by a recognized
external evaluation authority. Units normally employed as smaller
formations may base this assessment on evaluated subordinate unit
exercises.
4.c.2. T-2: the unit has satisfied the criteria for T-3 and
incorporated CBRN threat conditions into a MET-based unit level
exercise within the previous 12 months to achieve the baseline
level of CBRN readiness.
4.c.3. T-3: 80% or more of the unit is reported in MCTIMS as
proficient in CBRND Training & Readiness (T&R) events
contained in reference (b).
4.c.4. T-4: less than 80% of the unit is reported in MCTIMS as
proficient in CBRND T&R events outlined in reference (b).
4.d. Factor-3 CBRND Equipment Supply Level (S-level)
4.d.1. Units in possession of CBRND equipment shall determine and
report their CBRND Equipment S-level based on equipment physically
possessed and maintained on unit property records, per reference
(e). Units shall assess only those CBRND assets for which they
maintain direct accountability.
4.d.2. Non-deployed units that do not possess CBRND equipment and
whose equipment is maintained and stored in consolidated storage
facility, shall report S-6 for the S-Level and use the standardized
reason code SNM, equipment not measured, and the pre-populated
comment in the unit's readiness report.
4.e. Directed comments. In the CBRND overall comments box,
document the rationale for the reported CBRND level, including the
Unit's CBRND training status (Factor-1), METs accomplished in
simulated contaminated or CBRN threat environments (Factor-2), and
the condition and availability of CBRND equipment (Factor-3). The
overall CBRND level is a commander's subjective assessment based on
these factors and serves as the basis for the unit's overall CBRND
readiness assessment.
4.e.1. When multiple factors contribute to a reduced overall
rating, commanders shall select the reason code that best
communicates the shortfall.
5. PP&O has identified policy and terminology discrepancies in
references (c) and (d). These will be corrected and codified
during the next document review cycle. In the event of any conflict
related to CBRND readiness reporting, training, equipping, or
execution of evaluated exercises, this MARADMIN takes precedence
until reference (d) is updated and published. MSC and MEF Readiness
Officers and Chiefs, supported by CBRND personnel, will assist
subordinate unit Readiness Officers in implementing these reporting
standards. MSC and MEF Readiness Officers and Chiefs will collect
and consolidate all conflicting guidance and submit it to the CBRND
points of contact identified in this MARADMIN for deconfliction.
6. Release authorized by Lieutenant General Jay M. Bargeron, Deputy
Commandant, Plans, Policies, and Operations.//
