I think that is by the command’s discretion, from the way i’m interpreting AR 385-10, The Army Safety Program, pg 47, ch 10:
10-2 Required safety training
All Army personnel will be provided CRM training in those areas needed for a safe and efficient execution of their
task. This training shall specifically address—
a. The PPE required.
b. General safety requirements particular to the operation.
c. Risk mitigation techniques and controls.
d. Special safety requirements.
e. Lessons learned from previous operations.
f. Procedures for reporting and responding to accidents.
g. Identification of all known and perceived hazards.
10–3. Risk management in training
a. Leaders and managers are responsible for integrating CRM into all Army processes and operations. Safety and
occupational health staffs will provide mishap risk management component of CRM training, tools and other related
assistance. Risk reduction through application of controls by training, procedures, cautions, and warnings help reduce
accident probability.
b. Installations are to ensure that the CRM process is incorporated into training plans.
DA PAM 385-10, The Army Safety Program, does not expand on the ARs guidance at all but continually mentions that CRM should be integrated into all tasks.
