Phase IFoundation

Background

Overview

Critical for understanding India's national security policy, governance of defence, civil-military relations, and the institutional framework for strategic decision-making.

The Higher Defence Organisation (HDO) refers to the institutional framework and processes through which a nation's defence policy is formulated, implemented, and overseen. In India, it primarily involves the Ministry of Defence, the armed forces headquarters, and various inter-ministerial committees, aiming to ensure effective civil-military coordination and strategic planning.

Phase IIStatic core

Facts & tables

Key facts

Purpose

To ensure effective civil-military coordination, strategic planning, and resource allocation for national security.

Key Components

Ministry of Defence (MoD), Integrated Defence Staff (IDS), Service Headquarters (Army, Navy, Air Force), National Security Council (NSC) Secretariat.

Challenges

Historically, issues of civil-military imbalance, lack of integration between MoD and Service HQs, and bureaucratic hurdles have been identified.

Recent Reforms

Creation of the Chief of Defence Staff (CDS) and Department of Military Affairs (DMA) within MoD are significant steps towards integration.
