Some boxing mixed with wrestling/grappling training will be effective for self defence, though their is little emphasis on hand to hand combat in military doctrine, it simply is not worth the time and effort and it can cause lots of injuries, ie corneal abrasions which can effect eyesight (boxing/striking) and spinal injuries, knee injuries (wrestling/ju-jitsu).....I would rather see jawans spend more time on the firing range than on any exotic arts which in practical terms will have little or no effect in an actual battlefield.
