Which guidance provides information on personal duties and responsibilities concerning Weapons Systems Safety Rules (WSSR)?

The correct answer, which is DAFI 91-101, emphasizes the critical nature of personal duties and responsibilities regarding the safety and security of nuclear weapons systems within the Air Force. This instruction outlines the necessary protocols to ensure nuclear surety, which includes aspects such as handling, storage, and overall safety communication related to weapons systems.

DAFI 91-101 details the responsibilities of personnel involved in the nuclear weapons program, establishing a framework that guides military members in maintaining safety and security standards. It encapsulates essential training and operational procedures required to mitigate risks associated with nuclear weapons, thereby underscoring the importance of personal accountability in weapons systems safety.

In contrast, the other choices do not focus specifically on the personal responsibilities regarding Weapons Systems Safety Rules. DAFMAN 91-221 centers on investigations and reports related to weapons safety, DAFI 91-204 addresses the safety investigations and reports more broadly, and the Unit Committed Munitions List pertains to inventory and specifics of munitions, rather than detailing personal duties concerning safety.
