The Department of Military Affairs, headed by Chief of Defence Staff General Bipin Rawat, will have three joint secretaries from the Army, Navy and the Air Force, sources said on Wednesday.
From the civilian side, there are currently two IAS officers -- Rajeev Singh Thakur and Shantanu -- in the Department of Military Affairs (DMA).
With the appointment of three joint secretary-rank officers, the DMA will have a blend of civilian and military officers.
