Question 1: Develop, maintain and publish the CER References Tables in coordination with Joint Staff Targeting. <br> Validate tools, sources and methods used to display or calculate CERs, and accredit tools designed to estimate shielding effects

• Collateral Damage Estimation Methodology (CDM)
• Distinction
• Joint Technical Group for Munitions Effectiveness (JTCG/ME) (Correct answer)
• CDE Level 5 is also required when analysis determines

Correct answer: Joint Technical Group for Munitions Effectiveness (JTCG/ME)

JTCG/ME is the joint technical authority specifically chartered to publish CER Reference Tables and validate the tools and methods used to calculate and display collateral effects data. The CDM (Collateral Damage Estimation Methodology) is the broader analytical framework, not the specific body responsible for maintaining and accrediting the technical tables and shielding estimation tools.

Question 2: Fuzed for mitigation (delay fuze) and can include a heading recommendation.

• Principal Categories of Risk
• At CDE 4, the weapon must be (Correct answer)
• What is mitigation:
• Causes of Collateral Damage:

Correct answer: At CDE 4, the weapon must be

At CDE Level 4, the weapon must be fuzed for mitigation using a delay fuze, and a heading recommendation may be included to further reduce collateral effects. This represents a mandatory configuration requirement triggered at that specific analysis level — lower CDE levels do not impose these same fuze and heading constraints as a condition of the engagement.

Question 3: Even where one is justified in acting, one must not act in a way that is unreasonable or excessive

• Divisibility
• Additivity
• Distinction
• Proportionality (Correct answer)

Correct answer: Proportionality

Proportionality is the LOAC principle that prohibits using force that is excessive relative to the anticipated military advantage, even when an attack is otherwise lawful. Distinction is a separate principle governing the identification of combatants versus civilians. Divisibility and additivity are mathematical concepts with no relevance to the Law of Armed Conflict.

Question 4: An area formed by measuring a CER from either the edge of a target/element outline, the aim point for a point target, or edge of an engagement zone or artillery sheaf for an area target.

• Collateral Damage
• Collateral Objects
• Collateral Effects Radius (cer)
• Collateral Hazard Area (CHA)

The correct answer names the specific geometric zone defined by projecting the CER outward from a target's edge, aim point, or engagement zone boundary. This is distinct from the CER itself (which is just a radius value), from Collateral Damage (a broader outcome term), and from Collateral Objects (things that might be damaged). The zone name captures the resulting area of potential hazard, not the measurement used to construct it.

Question 5: The TE90 from either the Observer Adjusted (OA) or Predicted (P) method of engagement at less than 1/2 maximum range to target for each weapon system, shell, and fuze combination plus the WCER

• The 3A CER Reference Table provides two columns of individual warhead CERs
• The 3B CER Reference Table provides CERs based on the combination of
• The 3C CER Reference Table provides CERs based on
• Circular Error of Probability (CEP) (Correct answer)

Correct answer: Circular Error of Probability (CEP)

CEP (Circular Error of Probability) is calculated by combining the TE90 delivery error from the OA or Predicted method with the WCER to define the probability zone around the target. The 3A, 3B, and 3C CER Reference Tables are reference inputs that provide individual and combined warhead data used in the calculation — they are lookup tools, not the probability measure itself.

Question 6: List of objects or entities characterized as protected from the affects of military operations under international law and/or ROE

• No-Strike List is...
• Cdm product is an..
• No-Strike Entities (NSEs)
• Outline method

The correct answer is the formal term for the official roster of locations and entities legally protected from attack under international law and applicable ROE — a specific designation distinct from the No-Strike List (which appears in the wrong answers as a definition prompt) and No-Strike Entities. The term reflects the protected, off-limits status these targets hold during military operations.

Question 7: Mitigates against the Blast, Penetration, Debris and Cratering effects of warheads

• VT Fusing or air burst (Correct answer)
• Shielding
• Delay fusing
• Aimpoint offset

Correct answer: VT Fusing or air burst

VT (Variable Time) fuzing detonates the warhead above the surface as an air burst, which eliminates ground-contact effects — penetration, cratering, and surface debris — while also mitigating blast at ground level. Delay fuzing does the opposite, increasing penetration and cratering. Shielding reduces effects but cannot address all four categories. Aimpoint offset changes the impact location but does not alter how or where the weapon detonates relative to the surface.

Question 8: Initial Analysis

• CDE Level 1 (Correct answer)
• CDE Level 6
• CDE Level 3
• CDE Level 2

Correct answer: CDE Level 1

CDE Level 1 is the initial analysis stage, involving only a high-level assessment before detailed weaponeering begins. Levels 2 and 3 involve progressively more detailed analysis and mitigation planning, while Level 6 represents the most complex cases requiring the highest level of review and approval. The sequence moves from broad to highly specific as the CDE level increases.

Question 9: Definition: 1) Weapons malfunctions. 2) Unknown delivery errors. 3) Altered delivery tactics based operator judgement 4) Unknown transient civilian or noncombat personnel and/or equipment in the vicinity of a target area. 5) Secondary explosions (CDRs should remain cognizant of additional risk due to secondary explosions). 6) The use of cluster or ICM beyond CDE Level 3. 7) Unguided RAPs 8) Enhanced/Extended range artillery, mortar and naval guns are not addressed beyond CDE Level 3 (except 549 HERA w/ PGK fuze).

• CDE Level 4 CERs are calculated
• CDM is balance of..
• CDM does not account for: (Correct answer)
• As CDE levels increase....

Correct answer: CDM does not account for:

The CDM is a structured analytical tool, but it cannot model unpredictable real-world variables. Weapons malfunctions, human operator judgment calls, unknown civilians near targets, secondary explosions, and the use of certain munitions (cluster/ICM, unguided RAPs, extended-range artillery) beyond CDE Level 3 all fall outside what the CDM's inputs can account for. The other answer choices describe things the CDM does do — calculate CERs, balance risk, and support progressive planning across CDE levels.

Question 10: Weaponeering Analysis

• Cde Level 5
• CDE Level 3 (Correct answer)
• CDE Level 1 (Correct answer)
• CDE Level 1

Correct answer: CDE Level 3

CDE Level 3 is the threshold where weaponeering analysis is formally introduced, requiring planners to perform detailed technical calculations about weapon effects rather than relying on broader estimates. CDE Level 1 involves initial rough assessments that precede formal weaponeering, while CDE Level 5 represents the highest level of scrutiny well beyond where weaponeering analysis first enters the process.

Question 11: Operational imperatives and principal categories of risk

• Contributing factors to a CDR decision making
• The CDM supports the
• CDM helps CDRs balance the dynamic relationship between (Correct answer)
• Commander will apply the CDM for planning fires at the:

Correct answer: CDM helps CDRs balance the dynamic relationship between

The CDM's core function is to help commanders navigate the tension between operational imperatives (mission accomplishment) and the principal categories of risk (collateral damage). It is a decision-support framework for balancing these two competing considerations, not merely a list of contributing factors, a support tool for a single function, or a level-specific planning trigger.
