at the ceremony. Aside from these, the 2016 retreat saw the first appearance of marching bands from Central Armed Police Forces and the Delhi Police, plus performances by the Army Symphony Orchestra and Traditional Ensemble, the latter using a mix of traditional European and Indian instruments. The use of certain Indian instruments which require the musician to sit down while playing are a departure from the concept of the ceremony being one that is usually executed by musicians while marching.

The band master then marches to the President and requests permission to take the bands away, and informs that the closing ceremony is now complete. The bands march back playing a popular martial tune and the official march of the Armed Forces, Sare Jahan se Accha.

As the President's Bodyguard (PBG) horse-mounted troops arrive back in after the bands leave, the band stops as another band from the Army is stationed to play the national anthem again as the President receives the final salute for the day by the PBG, before the President and the
