Platoon commander Narendra Singh, a specialist instructor at CTJWC, sustained serious splinter injuries on his face in the explosion leading to his death, Kanker Superintendent of Police Jitendra Singh Meena told PTI.
At around 8.30 AM, a 'grenade throwing' training exercise was underway for trainees at the CTJWC, which is located around 150 km from here on Raipur-Jagdalpur road.
A grenade exploded close to Singh, who was supervising the training, causing splinter injuries on his face, the SP said.
Singh hailed from Nagaur district of Rajasthan.
An ex-Army man (non-commissioned officer), Singh had a vast experience in counter-IED (improvised explosive device) operations in the country as well as abroad, Meena said.
He had played a crucial role in defusing and destroying several landmines and IEDs during the past decade in insurgency-hit Bastar region.
