Final answer:
Chemlight requirement for FRIES rope refers to the specifications for attaching chemlights or glow sticks to a Fast Rope Insertion/Extraction System rope for visibility in low-light or dark conditions during military operations.
Step-by-step explanation:
The term Chemlight requirement for FRIES rope indicates the specifications for chemical light attachment to a Fast Rope Insertion/Extraction System (FRIES) rope used by military personnel. These chemlights, often called glow sticks, are used for marking and identification during night operations.
The requirements for attachment and the exact number of chemlights can depend on operational needs and specific military protocols. However, chemlights used with FRIES are typically secured at regular intervals along the rope for visibility, allowing assaulters to rapidly and safely descend in low-light or dark conditions.
