Roles and responsibilities

As the principal military authority of the Indian Armed Forces, the CDS is tasked with multiple mandates, which are elaborated in the undermentioned:^[10]

• Permanent Chairman, Chiefs of Staff Committee (PC-COSC)
  • Acts as the principal military advisor to the Minister of Defence on all affairs related to inter-service integration, coherence and functioning.^[7]
  • Exercises command authority over specific inter-service agencies, namely, the Defence Cyber Agency (DCyA), the Defence Space Agency (DSA) and the Armed Forces Special Operations Division (AFSOD) vis-à-vis the Integrated Defence Staff.^[11]
  • Responsible for the administration of the COSC on all disciplines related to, or requiring inter-service coordination, such as capability development, defence acquisition, doctrinal strategy, infrastructure, logistics and training.^[11]
• Ex-officio Secretary, Department of Military Affairs (Secretary-DMA)
  • Answerable to the Parliament an all affairs exclusively related to the armed forces.^[12]
  • Facilitates the restructuring of service-specific military commands to ensure the optimal utilization of resources by fostering jointness in operations, principally through the establishment of joint-service theatre commands.^[10]
  • Promotes jointness in procurement, training and staffing for the three armed services through joint-planning and integration of their respective requirements.^[10]

Appointment

Since its creation in January 2020, the office of CDS has customarily been held by a four-star officer from the three armed services, specifically, either a general, admiral or air chief marshal.^[6][13] The move to appoint a designate to the office is initiated by the Ministry of Defence (MoD), wherein the résumés of candidates recommended by the armed services are submitted for intense review, before being sent to the Appointments Committee of the Cabinet (ACC) - comprising the Prime Minister and the Minister of Defence, whereupon the appointment is finalized.^[14]

Notably, at the time of the office's creation, no fixed structure for an order of succession existed; thus, in the formative period of the office's existence, the senior-most service chief was recommended for appointment; the first instance of this was General Bipin Rawat, then the COAS and senior-most amongst the three chiefs.^[14][15] However, Rawat's unexpected death in 2021 whilst in tenure exposed this flaw; consequently, in June 2022, the MoD established a permanent set of appointment-cum-succession rules, stating that deemed four-star and three-star officers from the armed services, notwithstanding their states of being active or retired, would be deemed eligible candidates to be appointed to the office, provided they hadn't attained the age of 62 at the time of appointment.^[16]

As of 2022, the appointment regulations for CDS, whilst same for the three services, are classified distinctively, namely:

• Indian Army: Army (Amendment) Rules, 2022^[16]
• Indian Navy: Naval Ceremonial, Conditions of Service and Miscellaneous (Amendment) Regulations, 2022^[16]
• Indian Air Force: Air Force (Amendment) Regulations, 2022^[16]

The first time the regulations were actively exercised was in the appointment of Lieutenant General Anil Chauhan in September 2022; Chauhan, a former General Officer Commanding-in-Chief (GOC-in-C) in the IA who had retired in May 2021, was promptly recalled to active service and promoted to general.^[17][18]

Tenure

Under an initial set of regulations established by the MoD in December 2019,^[19] the service chiefs from the three services, namely, the COAS, the CNS and the CAS, having completed their mandated three-year tenure or having attained the age of 62, were deemed eligible to be appointed CDS, with the chosen designate tenuring the office to the maximum deemed age of 65; unlike the service chiefs, the CDS has no fixed tenure, but only an upper age limit.^[19] The aforementioned 2022 regulations expanded the office's reach, allowing both active and retired officers to occupy the office until the age of 65.^[16]

Previously, in the event of the an abrupt stoppage during the incumbent's tenure - by termination, resignation or sudden demise, the senior-most service chief was made acting-COSC and by extension, an ex officio-CDS until a suitable successor was appointed; this situation has occurred only once, when General Manoj Mukund Naravane, then-COAS of the IA, was made acting-COSC upon the death of General Rawat, the then-incumbent CDS.^[20]

Command flag

The office of CDS maintains a separate command flag, regardless of the incumbent appointee's parent service, symbolizing the independence of the position and its associated authority from the armed services.^[21] The flag comprising a maroon field - representing the inter-service jointness, furnished with the National Flag of India in the canton and the inter-service insignia of the Indian Armed Forces - comprising twin-crossed swords, an unfouled anchor and an eagle surrounded by an oak wreath in gold-furnishing.^[22] Similar to that of the service chiefs, this particular command flag is preferably displayed on the CDS's official car and at his office.^[23]

Accroutements

Whilst the CDS is a rotational appointment held by officers drawn from the three armed services, the CDS is an independent entity, thus mandating an exclusively distinct set of accoutrements.^[24] Notably, the CDS uniform allows the appointee to retain certain paraphernalia, such as the uniform of the appointee's parent service and its associated decorations; nonetheless, it lacks a lanyard, unlike the uniforms of the service chiefs.^[22]

In addition, the office mandates several distinct emendations, the primary of which are undermentioned:^[22]
