AR 15-6 addresses fact-finding, evidence gathering, allegations, command issues, and decisions based on investigative results. It establishes procedures for assessing information, applying a preponderance-of-the-evidence standard, completing actions timely, and addressing knowingly false or repeated frivolous allegations.
Preliminary inquiries, administrative investigations, and boards of officers are used to examine allegations or issues within a command or organization; gather facts; and help leaders make informed decisions. (paragraph 1-7)
The standard of proof for a preliminary inquiry, administrative investigation, and board of officers is preponderance of the evidence. (paragraph 1-9)
Unless specifically prescribed in another regulation, a timely manner is no more than 30 business days. (paragraph 2-1)
Personnel who are found to have knowingly submitted a false allegation, and the false allegation is what initially triggered an inquiry or investigation, may be subject to adverse administrative or punitive action. (paragraph 1-10)
Leaders are encouraged to explore all appropriate options they may have, rather than defaulting to an investigation in every case. (paragraph 1-7)
