Questions and answers

How often must EOD training events be sustained?

For collective or individual training events not executed and evaluated as part of the daily routine, leaders must ensure proficiency is sustained by requiring retraining of each event at or before expiration of the designated sustainment interval. (paragraph 1)

Who must receive CBRN defense training?

All personnel assigned to the FMF must be trained in chemical, biological, radiological, and nuclear (CBRN) defense in order to survive and continue their mission in this environment. (paragraph 1)

What safeties apply before a munition type is identified?

Use general EOD safeties until munition type is identified. (paragraph 3)

What must an EOD reconnaissance establish about explosive ordnance?

In order to determine the true nature of an explosive ordnance incident, to verify its categorization, and to plan procedures for disposing of the ordnance, every effort must be made to establish as early as possible the identity or, at least, the nature of the ordnance involved. (paragraph 3)
