At the ongoing DefExpo2020 in Lucknow, the Indian Army’s College of Military Engineering showcased the world's first helmet which can stop an AK-47 bullet round from a distance of 10 meters. While the helmet weighs only 1.4 kgs, the Indian Army’s College of Military Engineering is to join forces with a private firm for India's first and world's cheapest gunshot locator. It can locate exact location of bullet from distance of 400 meters which will help to locate and neutralise terrorists faster.
