The sortie routes of the the Indian Air Force (IAF) helicopters are being sanitised by UAVs in advance and it has doubled the strength of on-board 'Garuda' commandos to four everytime its Mi-17 choppers fly in remote and forested areas of Naxal violence affected states, official sources said.
A senior official in the anti-Naxal operations grid noted that the helicopters are under an "increased threat" from extremists.
A Court of Inquiry is already underway to ascertain the role of the IAF men involved in this operation.
The sortie routes of the IAF helicopters are now being sanitised by UAVs in advance and in many cases two helicopters fly the same path, with one flying alongside the other in a secure formation, the sources said.
"The anti-naxal operations are a dynamic state of affairs. There are regular intelligence inputs suggesting Naxal tactics and the helicopter sorties are surely under an increased threat," the official said.
The CRPF, which is the lead operations force against Maoists, is also deploying more men to secure the helipads during ascent and descent of helicopters that aid the operations by way of bringing in men and material besides evacuating casualties from conflict areas.
