Mehrangarh Fort
India
Mehrangarh Fort is strongest on Defensibility 9/10 — Exceptional wall mass, elevated rock, strengthened gates, outworks and an internal keep give the existing fort formidable passive defence and meaningful depth. It stops short of 10 because the very large heritage complex has multiple operational areas and is not a modern fully compartmentalised hardened facility.. Its clearest scored constraint is Isolation 1/10 — Jodhpur is immediately at the base of the fort. The 400-foot hill gives strong local defensive and approach advantages, but under the V2 separation rules that elevation must not be double-counted as regional isolation..

Field assessment

Bottom Line
For the fixed 20-person Base boundary, the most important endurance constraint is Resource Security 2/10 — Multiple current cafés and restaurants inside the fort establish real food-and-beverage inventory and preparation capability for immediate disruption, while the wider site retains documented historic water-management infrastructure. No authoritative source establishes a protected current potable-water source/storage/treatment pathway, durable internal food production or survival-energy independence after Jodhpur's systems fail. The evidence therefore supports a short-term-only resource position, not a stronger durable class..
Biggest Trade-off
The central trade-off is the catalogue's strongest evidenced dimension, Defensibility at 9/10, against its weakest evidenced dimension, Isolation at 1/10.
Most Likely Failure
The evaluation leaves this material failure condition unresolved: Current food/beverage service and historic water-management infrastructure are evidenced, but current independent potable source, protected storage, treatment and interruption tolerance for twenty people are not. Resource Security 2 credits the positive immediate starting position while retaining this limitation for package adjudication.
Score rationale
Why it scores this way
Defensibility · 9/10
Exceptional wall mass, elevated rock, strengthened gates, outworks and an internal keep give the existing fort formidable passive defence and meaningful depth. It stops short of 10 because the very large heritage complex has multiple operational areas and is not a modern fully compartmentalised hardened facility.
Advantages
- Positive credit is limited to what supports the Defensibility score of 9/10; the component rationale is: Exceptional wall mass, elevated rock, strengthened gates, outworks and an internal keep give the existing fort formidable passive defence and meaningful depth. It stops short of 10 because the very large heritage complex has multiple operational areas and is not a modern fully compartmentalised hardened facility.
Limitations
- Do not infer additional Defensibility capability outside the fixed Base boundary or beyond the recorded evidence.
Isolation · 1/10
Jodhpur is immediately at the base of the fort. The 400-foot hill gives strong local defensive and approach advantages, but under the V2 separation rules that elevation must not be double-counted as regional isolation.
Advantages
- Positive credit is limited to what supports the Isolation score of 1/10; the component rationale is: Jodhpur is immediately at the base of the fort. The 400-foot hill gives strong local defensive and approach advantages, but under the V2 separation rules that elevation must not be double-counted as regional isolation.
Limitations
- Do not infer additional Isolation capability outside the fixed Base boundary or beyond the recorded evidence.
Sustainability · 5/10
The fort is an actively maintained occupied complex with extensive rooms, courtyards and food-service spaces, so twenty people have a credible shelter and daily-life envelope. Heritage constraints, heat exposure and the absence of evidence for autonomous modern sanitation or residential systems keep it in the viable-but-constrained class.

Survival horizons
How survival changes over time
First 7 days: current defence/contact profile
First 7 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Defensibility 9/10 — Exceptional wall mass, elevated rock, strengthened gates, outworks and an internal keep give the existing fort formidable passive defence and meaningful depth. It stops short of 10 because the very large heritage complex has multiple operational areas and is not a modern fully compartmentalised hardened facility..
Risks
- The weaker current condition in this horizon is Exposure Control 8/10 — A high rocky position, massive walls, strengthened gates and layered outworks strongly channel and reveal approaches before boundary contact. Urban pressure can arrive from many directions around the hill, preventing an exceptional 9-10 approach-control score.; no better future state is assumed.
First 100 days: current habitat/capacity profile
First 100 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Population Capacity 7/10 — The fort is one of Rajasthan's largest, with extensive internal rooms, galleries, courtyards and active visitor facilities. The fixed twenty-person community is comfortably supportable in physical-space terms with meaningful headroom..
Risks
- The weaker current condition in this horizon is Sustainability 5/10 — The fort is an actively maintained occupied complex with extensive rooms, courtyards and food-service spaces, so twenty people have a credible shelter and daily-life envelope. Heritage constraints, heat exposure and the absence of evidence for autonomous modern sanitation or residential systems keep it in the viable-but-constrained class.; no better future state is assumed.
Long term: current resource/maintenance profile
Long Term
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Maintenance Resilience 6/10 — The fort's core protective value comes from massive passive masonry, gates and simple physical geometry rather than powered life-support machinery, and the site remains actively maintained. Heritage conservation is labour-intensive and some modern services will fail without outside support, but loss of specialist technology does not erase the basic shelter and defensive envelope..
Risks
- The weaker current condition in this horizon is Resource Security 2/10 — Multiple current cafés and restaurants inside the fort establish real food-and-beverage inventory and preparation capability for immediate disruption, while the wider site retains documented historic water-management infrastructure. No authoritative source establishes a protected current potable-water source/storage/treatment pathway, durable internal food production or survival-energy independence after Jodhpur's systems fail. The evidence therefore supports a short-term-only resource position, not a stronger durable class.; no better future state is assumed.
Tactical assessment
Practical Reality
Reality Check
Scores apply only to the defined Base and exactly 20 capable adults. Unknown, excluded or external assets are not credited as hidden capability.
Best Use
Within the evaluated boundary, treat Defensibility as the primary operational strength; do not promote that score into capabilities the evidence does not establish.
Key Risk
Resource Security is the key evidenced long-duration risk: Multiple current cafés and restaurants inside the fort establish real food-and-beverage inventory and preparation capability for immediate disruption, while the wider site retains documented historic water-management infrastructure. No authoritative source establishes a protected current potable-water source/storage/treatment pathway, durable internal food production or survival-energy independence after Jodhpur's systems fail. The evidence therefore supports a short-term-only resource position, not a stronger durable class.
