NEW DELHI: The Army is seriously considering recalibrating its counter-insurgency strategy in the militancy-hit northeast in the wake of an "over cautious" approach being adopted by its field units in the region following the Supreme Court 's strict orders to the CBI to ensure thorough probe into the alleged extrajudicial killings in Manipur , military sources said.They said the Army headquarters was "deeply worried" over the rising casualty figures on the part of the Army in Manipur as well as a marked slowdown in the intensity of its operations against militants in the state, where over 10 major militant groups are active. The top brass of the Army held a detailed deliberation last month to look at recalibration of operations since there appears to be a "manifested caution" being exercised because of the directives of the court on AFSPA-related cases, the sources said.The SC has passed a number of orders to the CBI in the last few months directing the central probe agency to probe the alleged extra-judicial killings and fake encounters by the Army, Assam Rifles and police in Manipur.
