What is the common examiner trap about Security & Defence in UPSC exams?

They may ask about the 'first' drone attack (June 26, 2021, on Jammu IAF) versus the 'first' drone incursion for smuggling (earlier, around 2020). They might also swap the names of Indian counter-drone systems (e.g., D-4 vs. KAVACH) or the number of drones in Op Sindoor (300-400).

What should UPSC aspirants remember about Security & Defence for Prelims?

1. Target this Data: Infiltration bids dropped from 143 (2018) to 34 (2021). 2. Target this Nodal Body: Border Security Force (BSF) raised its first drone squadron. 3. Target this Legal Point: Operation Sindoor - the first use of drone swarms in an Indo-Pak conflict.

Drone Warfare Reshapes Indo-Pak Border Security: 300-400 Drone Swarms Used in Op Sindoor, Infiltration Drops 76% (2018-2021)

Q: Which central armed police force is primarily responsible for India's border security with Pakistan and raised its first drone squadron as mentioned in the article?

Border Security Force (BSF), The article explicitly states that the BSF, which is primarily responsible for border security, raised its first drone squadron last year. The BSF is tasked with guarding India's borders with Pakistan and Bangladesh.

Q: Consider the following statements regarding the use of drones along the Indo-Pak border: 1. The first terror attack using drones to airdrop bombs on a major Indian security installation occurred at the Jammu Air Force station in June 2021. 2. Operation Sindoor marked the first use of drone swarms by Pakistan in a conflict with India, involving nearly 500-600 drones. 3. Indian countermeasures include the indigenous anti-drone D-4 system and a laser-based system called KAVACH deployed in Jammu & Kashmir. Which of the statements given above is/are correct?

Both 1 and 3, Statement 1 is correct: the article confirms the first drone terror attack was on the IAF station in Jammu on June 26, 2021. Statement 2 is incorrect: the article says Pakistan used 300-400 drones in Operation Sindoor, not 500-600. Statement 3 is correct: the article mentions the indigenous D-4 anti-drone system and the KAVACH laser system deployed in J&K.

Q: According to the article, what was the approximate value of narcotics seized by J&K Police and other agencies across the Union Territory over the past five years?

Around ₹30,000 crore, The article states that security agencies have seized nearly 68,000 kg of narcotics valued at around ₹30,000 crore across J&K over the past five years. This highlights the scale of the narcotics smuggling issue linked to drone droppings.

Q: What is identified in the article as a primary reason for Pakistan's shift to using drones for cross-border activities?

Because drones are easier to penetrate than fortified ground borders, Former J&K DGP Kuldeep Khoda is quoted stating that Pakistan turned to drones because border fencing, night vision devices, and other monitoring systems made ground infiltration nearly impossible. Drones provided an easier means to penetrate and deliver weapons and narcotics.

What This Article Covers

1.First major drone terror attack on IAF station in Jammu occurred on June 26, 2021, marking a paradigm shift in Pakistan-based terror tactics.

2.Operation Sindoor saw first use of drone swarms in Indo-Pak conflict, with 300-400 drones targeting locations from Kashmir to Gujarat in May last year.

3.India's countermeasures include indigenous KAVACH laser, D-4 anti-drone systems, MANPADS, DEWs, and the BSF raising its first drone squadron.

The Big Picture

Prelims · HighMains · High

Drones have fundamentally altered border warfare between India and Pakistan, shifting threats from ground to air. Pakistan's use of drone swarms for weapons/narcotics drops has forced India to deploy advanced counter-drone systems like SkyStriker, HAROP, and indigenous D-4, leading to a 76% drop in human infiltration attempts from 2018 to 2021.

Paradigm Shift in Warfare

The June 2021 drone attack on Jammu IAF station marked the first use of drones for airdropping bombs on a major Indian security installation, rendering traditional border security measures inadequate.

⚔️

Operation Sindoor & Drone Swarms

Pakistan launched 300-400 drone swarms targeting dozens of locations from Kashmir to Gujarat in May last year, marking the first large-scale use of this tactic in an Indo-Pak conflict.

🛡️

India's Tech Countermeasures

Indian forces deployed SkyStriker Kamikaze drones, HAROP, Nagastra-1, and indigenous systems like D-4 anti-drone and KAVACH laser to detect and neutralize threats, while BSF raised its first drone squadron.

Detailed Analysis & Strategic Depth

Context / Background

Drone usage by Pakistan-based groups along the LoC and IB began escalating around 2020, primarily for smuggling. The 2021 Jammu IAF attack demonstrated their offensive potential, forcing a complete re-evaluation of border security strategies that previously relied on physical fencing, patrolling, and ground-based sensors.

Core Analysis & Implications

Drones have created a multi-domain threat: airdropping weapons/narcotics, conducting surveillance, and guiding militants. This has expanded the security perimeter beyond the traditional 5-km border belt, requiring 24x7 aerial vigilance and joint patrols in hinterlands. While counter-drone tech has reduced infiltration, the low-cost, high-deniability nature of drones presents a persistent asymmetric challenge.

Future Outlook / Way Forward

The focus will be on integrating advanced sensors (thermal, UGS, radar), developing jam-resistant tethered drones, and continuous training of 'tech-savvy' soldiers. However, vigilance against Pakistan's evolving hybrid tactics—using drones as distraction while attempting ground infiltration—remains critical. Investment in indigenous R&D for counter-drone systems is a strategic imperative.
