Former UP CM Mayawati and Tmilnadu CM Jayalalita refused to have women as their shadows. The National Security Guard on Tuesday for the first time showcased its women commando unit, trained in all forms of combat and ready to take on all contingencies. Sources said the 25-member unit was raised to provide VIP security. However, Mayawati and Jayalalitha, who have been accorded Z+ security with NSG's Black Cats guarding them, did not show much enthusiasm for the new plan, sources said. Both are still guarded by NSG men. Security attachment for a VIP is decided by the Centre on the basis of threat perception assessed by intelligence agencies. There is no official provision for VIPs to decide what kind of security contingent guards them. Sources said the force's women commando unit has been raised through the same training as that of male commandos and has all the skills of their male counterparts.
