A US Naval Academy has carried out a 'secret' air-to-ground mission, dropping ping pong balls and messages ahead of their annual American Football match.
The US Army's Black Knights and the Navy's Midshipmen head to Philadelphia on Saturday, meeting for the 123rd time since their American Football rivalry began in 1890.
In what has become an annual pre-match tradition, whereby opposing US military teams will try to troll each other on social media, they then share the prank video with their rivals.
This year, the US Navy used an aircraft to bombard their rivals from above with messages reading "Beat Army," and "Fly Navy", others claimed.
The US Navy mission was carried out in the same way Second World War propaganda messages and leaflets were dropped during the war.
In an official statement released on Tuesday, the Naval Academy confirmed that "midshipmen from the Class of 2023 successfully conducted an air-to-ground spirit mission over the US Military Academy at West Point, New York, ahead of Saturday's 123rd Army-Navy Game.
"Twelve delivery passes dropped "Beat Army" and "Fly Navy" leaflets, along with ping pong balls, over Army West Point's, The Apron."
According to the statement, US Army cadets could be seen "breaking formation" and "running for cover", as the brightly coloured ping pong balls fell from the sky and among those on parade.
The stunt comes after another United States Army American Football team 'blew up' the US Navy's goat mascot and posted the hilarious video online.
