Since Mark Harmon, Gibbs, is a producer of this show and Donald Bellisario creates the majority of the shows off of military stories, the most famous sniper in the world of the Vietnam era, well known to all Marines in training, that they would get his kill total correct. So the writer and the rest of the staff are either clearly ignorant or dyslexic. Anybody who watch this show and is done even the most basic reading about marines knows this, it's pathetic that someone is making as much money as Harmon and he does no background study on the subject and allows himself to look like an idiot.
One of the other things it really bothers me is how many time shows like NCIS Or chasing somebody and they end up not pursuing them and they sort of look at each other and say he got away. Whether it's on foot or in a car the fact is that person is only 15 seconds ahead of them, they're chasing someone that's on their most wanted list they don't have back up surrounding a grid around the blocks where the operation is happening and they don't have a helicopter in the air and local PD helping also? None of these people should've ever gotten away and it's almost seems like every episode. And then you see him with their guns out screaming at someone saying NCIS, or police stop or I'll shoot and of course they never knew if they're running away. Or the bad guy tries to hit them with a car that's the use of a deadly weapon you can shoot now. The shows are so unrealistic Can't really bear to watch anymore
