Amritsar: Operation Sindoor applied brakes on the drone intrusion for some time, but Pakistani smugglers have returned with advanced strategy and are accurately pushing the drone deeply into Indian territory.“Post OP Sindoor, cross-border drone was a temporary lull in infiltration. However, these activities are now resumed with greater accuracy as Pakistani smugglers are deploying deep drones entering Indian territory to release drugs, weapons and ammunition,” said BSF Digu Vidyarthi.According to sources, the earlier aircraft was often close to the international border – around one kilometer – but now the Pakistani drones are seen 2 km to 2.5 km or more within Indian territory.Pak drones fly at high altitude near the border to avoid detectionA source said, “During the OP vermilion, the priorities were widespread-it was not only about curbing the border crossing, but more about stopping drone and missile attacks. More about the border smuggling activity declined significantly because Pakistani smugglers decreased to recur the decline with local renovation on the Indian side.”But then, why has there an increase in cross -border drone infiltration after OP vermilion? According to sources, Pakistani smugglers have equipped themselves with more advanced Chinese drones, while the anti-draone technology posted on the Indian border is not as effective as it should be.Currently, the drone is often seen only their sound or visually, after which the information is released to the anti-drain team. The system is then activated to jam the drone or to serious its connection with the operator in Pakistan. Sources said that such interceptors should be placed every few kilometers every few kilometers along the international border in Punjab to detect an upcoming drone – its direction, speed, height and other details – so that it can be blocked and forced into the ground, the sources said.Asked that Pakistani smugglers were trying to push the drone deeply into the Indian territory, stating that the BSF had patrolled and tightened the security and surveillance after the OP Sindoor. By sending deeply to Indian territory, smugglers have to ensure that the receiver (collectors) are further removed from the international border, so that the BSF patrol can reduce the possibility of detection.Nowadays, Pakistani drone pilots start blowing drones at high height near the border to avoid detection. Once drones cross into Indian territory, they fall to low altitude and follow the zigzag routes for monitoring. After reaching the drop zone, drones also intentionally crashes.
