(AP) — Some Nebraska veterans have been sharing their war stories with a researcher from the University of Nebraska-Lincoln.

In some cases, the veterans are telling Brian O’Grady about things they’ve never told their families.

O’Grady says “it’s easier for them to talk to someone they’re not emotionally connected with.” But, he says, he’s given copies of the interviews to their families.

He’s focused on World War II vets but also has talked to men who fought in the Korean or Vietnam wars and to a veteran of Operation Iraqi Freedom.

O’Grady plans to publish the stories and may donate the recordings to an archive.
