Why did the secret service call John F. Kennedy lancer?

The Secret Service code name "Lancer" for John F. Kennedy was derived from his association with the "Lancer" horse, which symbolizes strength and nobility. The practice of assigning code names to protect the identities of public figures and enhance security began in the early 20th century. Each code name is often chosen based on personal traits, interests, or historical references. In Kennedy's case, "Lancer" reflected both his youthful vigor and his status as a leader.
