All matters pertaining to a mishap that can be used for legal or administrative action are documented during what type of investigation?

The correct answer pertains to the specifics of a Judge Advocate General (JAG) investigation, which is designed to address potential legal issues that may arise from mishaps. These investigations focus on collecting evidence and documenting facts related to incidents in a manner that is suitable for potential legal or administrative action.

The JAG investigations ensure that all aspects that could lead to legal ramifications are thoroughly examined and documented, maintaining a high level of detail and formality. This type of investigation is critical for maintaining discipline, accountability, and adherence to military law, which can be crucial in determining the appropriate actions following a mishap.

In contrast, other types of investigations, such as command investigations and administrative investigations, do not typically focus on the legal aspect to the same extent. Command investigations may prioritize overall command responsibility and decision-making processes, while administrative investigations generally assess compliance with policies or procedures rather than legal viability. Safety investigations primarily aim to prevent future incidents by identifying hazards and recommending safety measures, rather than preparing evidence for legal considerations.
