Border Infrastructure; Air Defence; Counter-Drone Systems; Dual-Use Infrastructure
Introduction
One year after Operation Sindoor (7th May), India has intensified efforts to build underground military infrastructure and strengthen air defence systems. Lessons from recent conflicts have also pushed reforms in troop deployment, drone warfare, and counter-drone capabilities.

Conclusion
One year after Operation Sindoor, India has focused on underground military infrastructure and integrated air defence systems. Rising drone threats also highlight the need for stronger counter-UAS capabilities, more S-400 systems, and faster progress on Project Kusha. The key lesson is that passive and active defence must develop together.
UPSC Mains Practice Question
GS Paper III – Indian Economy (Inclusive Growth & Employment) | GS Paper I – Society (Poverty & Inequality)
Measurement of Inequality; Labour Codes; Rural Employment Guarantee; Data Comparability
Introduction
Recent policy changes, including the new Labour Codes and the replacement of MGNREGA with the Viksit Bharat Rozgar Mission, have raised concerns over protections for informal and rural workers.
Although official data suggests inequality has declined since the early 2010s, doubts over data comparability and reliability remain. The apparent ‘low’ inequality may hide widening gaps in wealth, consumption, and access to essential services.

The Official Narrative: Declining Inequality?

Policy Responses:
Conclusion
Official data suggests inequality in India has declined since the early 2010s, but this may mask deeper disparities. Changes in survey methods limit comparison over time, while new Labour Codes and the replacement of MGNREGA raise concerns over worker protections and rural employment security.
Since consumption surveys fail to capture wealth concentration, actual inequality is likely far higher. Policymakers must ensure comparable data, publish regular wealth estimates, and address unequal access to opportunities and services—not just consumption levels.
