You must have noticed that all disability are not considered for disability pension. All disability not considered as attributable / aggravated by military service. Here is the detailed discussion based on the new ER GMO 2023. The issue of Disability Compensation, Disability Pension, and Death Benefits for Armed Forces Personnel has become an important topic after the implementation of Entitlement Rules 2023 (ER-2023) and Guide to Medical Officers 2023 (GMO-2023) by the Ministry of Defence.
Several Ex-servicemen Associations raised concerns that the new rules have narrowed the scope of benefits, while the Ministry has clarified that the revised provisions are actually more scientific, evidence-based, and beneficial.
This article gives a detailed analysis of the new rules, controversies, and official clarifications.
Why Were New Rules Introduced?
According to the Ministry, medical science has advanced significantly. Earlier broad presumptions were no longer considered sufficient in every case.
The Government stated that:
- Some diseases cannot be detected during recruitment medical examination.
- Certain dormant diseases may remain hidden at enrolment stage.
- Some hereditary, congenital, or constitutional diseases may develop during service naturally.
- Therefore, merely developing a disease during service does not automatically prove that it was caused or aggravated by military service.
Hence, entitlement now depends on documentary evidence + clinical evidence + causal connection.

What is Attributability and Aggravation?
Attributability
A disease/injury is considered attributable when it is directly caused by military service conditions.
Aggravation
A pre-existing or natural disease becomes worse due to military service conditions.
These two principles determine disability compensation and death benefits.
Major Change Under Rule 11(b)(2)
Under ER-2023, for a disease to be accepted as attributable to service, two conditions must be satisfied simultaneously:
(i) Disease must arise during service period
AND
(ii) Disease must be caused by service conditions such as:
- Active operations
- High altitude areas
- Extreme cold / hot climate
- Extreme physical exertion
- Exposure to infections
- Chemicals
- Ionizing radiation
Why This Became Controversial
Ex-servicemen Associations argued that earlier rules were more liberal. Under old provisions:
- Benefit of doubt was given to soldiers.
- Disabilities arising during service were generally presumed service-connected.
- Even peace area cases were often considered attributable/aggravated.
They cited Supreme Court rulings that disability benefits cannot be denied merely because the disease occurred in a peace station.
Ministry Clarification: Peace Area vs Field Area
The Ministry clarified that the new rules do not distinguish between Peace Area and Field Area.
According to the Government:
- The focus is on service conditions, not geographical location.
- Extreme physical exertion or hazardous exposure can occur anywhere.
- Therefore, disability compensation can still apply in peace stations if service conditions caused the disease.
This is a crucial clarification.
Heart Disease / Coronary Artery Disease Rules
Earlier GMO 2008
Ischemic Heart Disease (IHD) was attributable if:
- Severe trauma or exceptional physical/mental stress occurred.
- Symptoms developed within 24–48 hours.
- Occurred during Field Ops / CI Ops / High Altitude Area.
New GMO 2023
Coronary Artery Disease (CAD) is attributable if:
(a) Onset while serving in:
- High Altitude Area (HAA)
- Within 3 months after de-induction from HAA
- Onboard Ships for 3 months
- Submarines for 1 month
(b) Onset during or within 72 hours of heavy physical exertion
(Above 7 METS due to service requirements)
(c) Onset during active operations
Why Ministry Says New Rules Are Better
Government claims GMO-2023 is more beneficial because:
- Stress window increased from 48 hrs to 72 hrs
- Added 3-month de-induction period after HAA posting
- Included ship/submarine conditions
- More objective criteria defined
Thus, according to the Ministry, these changes expand entitlement.
Cancer Cases: What Changed?
Concern Raised
Associations alleged that earlier most cancers (except smoking-related) could be considered aggravated if worsened during service.
Now only cancers linked to:
- Radiation exposure
- Chemical exposure during service
are clearly attributable.
Ministry Reply
Government stated there is no material adverse change in cancer entitlement compared to earlier rules.
Diabetes Mellitus
Concern Raised
Associations said all diabetes categories were removed from service linkage despite stress being medically known to affect insulin levels.
Ministry Stand
Medical science now better identifies aggravating factors. GMO-2023 specifically defines conditions under which diabetes may be aggravated by service.
Thus, according to the Ministry, criteria have become clearer and broader.
Hypertension
Old Position (GMO 2008)
Primary Hypertension was generally treated only as aggravated, not attributable.
New Position (GMO 2023)
Now Hypertension may be:
- Attributable to service
- Aggravated by service
Examples:
- High altitude
- Active operations
- Ship/submarine service
- Worsening due to target organ damage from service stress
Hence Ministry says this is more favourable.
Bronchial Asthma, PIVD, Spondylosis
Objections Raised
Associations claimed these conditions were historically linked with service stress but now weakened in the new list.
Government Reply
The criteria have been reformed and medically updated according to latest scientific knowledge.
Cases can still be accepted if:
- Specific service conditions worsened the disease
- Causal connection is proved
Core Principle in GMO-2023
Even if a disease is not specifically listed, it may still be accepted if evidence shows:
- Onset was hastened by military service, OR
- Disease worsened due to military service conditions
This is an important safeguard.
Effective Date
ER-2023 and GMO-2023 apply to:
- Death cases reported on or after 21 September 2023
- Disability cases recorded on or after 21 September 2023
Earlier cases may be governed by previous applicable rules depending on circumstances.
Why This Issue Matters
For Armed Forces Personnel, disability benefits are not charity—they are compensation for risks undertaken in national service.
Therefore rules must balance:
Soldier Welfare
with
Medical Evidence and Administrative Fairness
Key Debate: Liberal Presumption vs Scientific Proof
This entire controversy revolves around two approaches:
Earlier Approach
- Presumption in favour of soldier
- Benefit of doubt
New Approach
- Medical evidence based
- Defined criteria
- Causal connection required
Both sides have strong arguments.
What Service Personnel Should Do
If facing rejection in disability claim:
- Preserve service records
- Maintain medical documents
- Note posting details (HAA / Ops / Ships etc.)
- Keep evidence of stressful service conditions
- File appeal/review in time
- Use tribunal/legal remedy if needed
Final Conclusion
The Ministry maintains that ER-2023 and GMO-2023 are more beneficial and scientifically updated, while veterans’ groups fear that stricter conditions may reduce benefits in some cases.
The real impact will depend on how fairly Medical Boards and Competent Authorities interpret these rules in practice.
For soldiers and veterans, awareness of these provisions is now more important than ever.
