What is NOT a potential SOSMIL maintenance activity?

Crew training sessions are not considered a potential SOSMIL maintenance activity because SOSMIL typically focuses on specific maintenance and operational support tasks necessary to maintain equipment or systems. Maintenance activities generally involve direct interactions with the machinery, such as fueling, battery changes, or diver operations, which are integral to ensuring operational readiness and safety.

On the other hand, crew training sessions usually serve an educational purpose and are designed to enhance the competencies and skills of personnel, rather than being a direct maintenance task associated with equipment or systems. Training is essential in the overall operational context but does not fall under the routine maintenance categorization typically outlined in SOSMIL procedures.
