Headquarters Integrated Defence Staff marked its Silver Jubilee, 25 years since it was set up in New Delhi on 1 October 2001, observed as Tri-Service Day.

Why in News
On 1 October 2026 Headquarters Integrated Defence Staff celebrated 25 years of jointness and integration, its Silver Jubilee, with Trishakti Manthan, a commemorative book, a film and CDS Unit Citations.
Headquarters Integrated Defence Staff (HQ IDS) marked its Silver Jubilee, completing 25 years since it was raised in New Delhi on 1 October 2001. The day is observed as Tri-Service Day.
Theme and the main event
The celebrations carried the theme “Future readiness through jointness and Integration”. HQ IDS held an event called Trishakti Manthan, addressed by the Chief of Defence Staff and Secretary, Department of Military Affairs, General N. S. Raja Subramani, and by the Chief of Integrated Defence Staff to the Chairman, Chiefs of Staff Committee, Air Marshal Tejinder Singh. Speakers traced the organisation’s part in operational preparedness through joint doctrines, joint training frameworks, integrated exercises and better coordinated Humanitarian Assistance and Disaster Relief mechanisms.
What was released and conferred
- A Silver Jubilee Book recording the organisation’s growth and achievements over 25 years
- A film on the milestones reached since it was established
- CDS Unit Citations given to personnel for strengthening jointness and integration
- A wreath laying ceremony at the National War Memorial and Museum for those who made the supreme sacrifice
The role it has played
HQ IDS has prepared the armed forces for newer domains such as cyber, space and artificial intelligence, and has worked with research bodies, academia and industry to speed up indigenous capability in keeping with Atmanirbharta in defence. Its institutional platforms include Ran Samwad, the Joint Commanders’ Conference (JCC) and the Combined Operational Review and Evaluation (CORE) Programme, which allow structured discussion of current security challenges and sharpen joint warfighting across land, maritime, air, space, cyber and cognitive domains.
Why it matters
Over two and a half decades the organisation has grown into the apex body driving jointness, integration and synergy among the three Services, with its focus on building capability and on employing combat power jointly in line with national security goals. For aspirants the founding date, the Silver Jubilee theme and the two senior appointments named above are the facts worth fixing.

Practice Questions
Headquarters Integrated Defence Staff was raised on which date, observed as Tri-Service Day?
- A.1 October 2001
- B.1 October 1999
- C.15 January 2002
- D.1 January 2020
Show answer
Correct answer: A. 1 October 2001
Explanation
The correct answer is 1 October 2001. HQ IDS was established in New Delhi on that date, and the day is observed every year as Tri-Service Day; the organisation therefore completed 25 years and celebrated its Silver Jubilee under the theme of future readiness through jointness and integration. Option B is wrong because the body did not exist in that year, and an earlier date would not fit a Silver Jubilee falling now. Option C is wrong because that date belongs to no part of this story, and the founding was in October, not January. Option D is wrong because the post of Chief of Defence Staff and the Department of Military Affairs came much later than the raising of HQ IDS, so a date from this decade cannot be its founding day. Fix the date along with the name Tri-Service Day.
What was the theme of the HQ IDS Silver Jubilee celebrations?
- A.“Atmanirbharta in Defence”
- B.“Future readiness through jointness and Integration”
- C.“Joint Training for Joint Victory”
- D.“Synergy in Space and Cyber”
Show answer
Correct answer: B. “Future readiness through jointness and Integration”
Explanation
The correct answer is “Future readiness through jointness and Integration”. Under this theme HQ IDS organised Trishakti Manthan, released a Silver Jubilee Book and a film on its milestones, and conferred CDS Unit Citations on personnel. Option A is wrong because Atmanirbharta in defence is the wider national goal that HQ IDS supports by working with research organisations, academia and industry on indigenous capability, but it was not the jubilee theme. Option C is wrong because joint training frameworks were only one of the contributions discussed at the event and no such slogan was adopted. Option D is wrong because cyber and space are among the emerging domains the organisation prepares the forces for, yet neither phrase formed the theme. Themes are a favourite one-mark question, so the exact wording matters.
Which of these is NOT a platform used by HQ IDS to strengthen jointness?
- A.Ran Samwad
- B.Joint Commanders’ Conference
- C.Combined Operational Review and Evaluation Programme
- D.Trishakti Manthan held as a permanent annual review body
Show answer
Correct answer: D. Trishakti Manthan held as a permanent annual review body
Explanation
The correct answer is Trishakti Manthan held as a permanent annual review body. Trishakti Manthan was the event organised as part of the Silver Jubilee, featuring addresses by the Chief of Defence Staff and by the Chief of Integrated Defence Staff, and it is not described as a standing institutional mechanism of the kind listed in the other options. Option A is wrong as an answer because Ran Samwad is indeed named among the platforms that strengthen institutional mechanisms for jointness. Option B is wrong as an answer for the same reason, the Joint Commanders’ Conference being one of those platforms. Option C is likewise a genuine platform, the Combined Operational Review and Evaluation Programme, which supports structured deliberation on security challenges and improves joint warfighting across land, maritime, air, space, cyber and cognitive domains.
