74.A person who is subject to service law commits an offence if, without lawful authority, he discloses to someone else information which he knows or has reasonable cause to believe might be useful to an enemy. Service personnel might be authorised to make a particular disclosure or have general authority to disclose certain information; an obvious example of authorised disclosure would be to pass necessary information or orders to those in the same command. Conduct by service personnel which, in England and Wales, would be an offence under the Official Secrets Acts 1911 to 1989 will be a criminal conduct offence within section 42 of the Act, and more serious offences relating to disclosure of information are likely to be prosecuted under that section.
