In June 2018, 92-year-old Russell Posey Sr. becomes the latest to be admitted, but his experience won't be routine.

My sister called me one morning and said that my father was not acting right.

He was sick, so she took him to a VA 'cause that's where his doctors were.

They didn't diagnose him with anything for the first day.

He was in ICU, had low blood pressure with low kidney response.

They said his organs were trying to shut down.

Eventually, they determined that he had pneumonia, and, um, they treated him for it.

Upon completion, his unit was selected to perform a dangerous mission.
