More than the Apache, the requirement is to have drones with tactical SAR capability. The north east is covered with dense forests. And like
@Abingdonboy rightly pointed out, the need is for an ability to look under foliage and work under the rainforest conditions prevalent there. A good option would be the ScanEagle which was offered to India. This has the SAR capability and can be used in mountainous terrain and does not need a landing strip. It could also be used for IED and mine detection during CS ops.
