Vijay Diwas is observed on 16th December every year to mark India's victory over Pakistan in 1971 war.
On 16th December 1971, the chief of the Pakistani forces had surrendered unconditionally to the allied forces consisting of Indian Army and Mukti Bahini in Dhaka.
The end of the 14-day war resulted in subsequent secession of East Pakistan into Bangladesh.
To mark the event, Indian Air Force has also felicitated a team of 25 Air Warriors for undertaking a running expedition from Kargil to Kohima- aptly named as K2K Ultra Marathon-Glory Run.
