New Delhi: The Maoist insurgency has engulfed large swathes of Chhattisgarh, Odisha, Andhra Pradesh, Maharashtra, Jharkhand and Bihar since 2004.
This year's deadly attack on Darbha valley, that killed 24 Congress leaders including former state minister Mahendra Karma and the Chhattisgarh Congress chief Nand Kumar Patel has jolted the security forces out of their complacency.
To counter such attacks, the government made a special force in 2008 called COBRA.
Cobra force stands for Commando Battalion for Resolute Action. It's a specialized force of the CRPF meant to counter Maoist insurgency.
