| Administrative / biographical background: |
On 1 April 1964 the Defence Intelligence Staff [DIS] was created to group together the pre-1964 service intelligence departments and the Joint Intelligence Bureau under a Director-General of Intelligence. Broadly speaking, the new DIS carried out the same duties as its predecessors, albeit within a tri-service framework: that is, to provide the Ministry of Defence with a central unified intelligence organization which could provide objective all-source assessments of defence intelligence matters in peace, crisis and war. Its primary function is to give warning of preparations for war or attack by a potential enemy. Much of the DIS's work is devoted to military subjects such as doctrine, tactics, force organizations and orders of battle (generally known as ORBATS), weapons and capabilities. In addition, other issues are covered so as to achieve a more complete picture: defence industries; economic aspects of defence; science and technology; nuclear, chemical and biological capabilities; arms traffic, control and verification. |
