In one of the deadliest attacks on the Army in recent years, 18 jawans were killed and 19 injured as heavily armed militants stormed a battalion headquarters of the force in Uri town in the wee hours on September 18.
The attack has left the nation benumbed and prompted tributes to the fallen soldiers from various parts of the country.
