(a) Confidentiality of information: (1) A covered attorney shall not reveal information relating to representation of a client unless the client consents after consultation, except for disclosures that are impliedly authorized in order to carry out the representation, and except as stated in paragraphs (a)(2) and (a)(3) of this section.
(2) A covered attorney shall reveal such information to the extent the covered attorney reasonably believes necessary to prevent the client from committing a criminal act that the covered attorney believes is likely to result in imminent death or substantial bodily harm, or significant impairment of national security or the readiness or capability of a military unit, vessel, aircraft, or weapon system.
(3) A covered attorney may reveal such information to the extent the covered attorney reasonably believes necessary to establish a claim or defense on behalf of the covered attorney in a controversy between the covered attorney and the client, to establish a defense to a criminal charge or civil claim against the attorney based upon conduct in which the client was involved, or to respond to allegations in any proceeding concerning the attorney's representation of the client.
(b) Conduct likely to result in the significant impairment of national security or the readiness or capability of a military unit, vessel, aircraft, or weapon system include, but are not limited to: Divulging the classified location of a special operations unit such that the lives of members of the unit are placed in immediate danger; sabotaging a vessel or aircraft to the extent that the vessel or aircraft could not conduct an assigned mission, or that the vessel or aircraft and crew could be lost; and compromising the security of a weapons site such that the weapons are likely to be stolen or detonated. Paragraph (a)(2) of this section is not intended to and does not mandate the disclosure of conduct which may have a slight impact on the readiness or capability of a unit, vessel, aircraft, or weapon system. Examples of such conduct are: absence without authority from a peacetime training exercise; intentional damage to an individually assigned weapon; and intentional minor damage to military property.
