5 Seasons Later, Every NCIS Episode Still Secretly Honors Mark Harmon's Leroy Jethro Gibbs

While NCIShas been without Leroy Jethro Gibbs (Mark Harmon) for years, the series still takes painstaking care of its original leader with a behind-the-scenes ritual that honors him years after his departure. For nearly two decades, NCIS viewers watched as Gibbs led the MCRT with a set of rules to live by and expert precision. Throughout the show's first era, Gibbs was the leader who found himself ready for any case, but didn't give his team much by way of words. Instead, the MCRT was left with Gibbs' expertise and his rules, which accounted for nearly every scenario possible.
