Passing out is the official graduation ceremony following the completion of a course by military or other uniformed service personnel at their respective training school, college, or military academy, largely in Commonwealth nations.[1] Soldiers, sailors, or airmen take part in a passing out military parade upon completion of a basic training course.[2] The military parade during the 'passing out' ceremony may also consist of military bands, and other displays of synchronisation discipline such as a flypast, which may also include acrobatics.[3]
