Excerpt: This is an overview of the regular, recurring, and other characters of the TV series NCIS. Supervisory Special Agent Leroy Jethro Gibbs (portrayed by Mark Harmon) was born in Stillwater, Pennsylvania to Jackson Gibbs and Ann Gibbs. He joined the United States Marine Corps in 1976 and became a Scout Sniper instead of attending college.
