I started the show again, and she said, "That's him, Gregory Gadson. I remember the name from when we lived in Fairfax. He was the Commander of Fort Belvoir and featured in a newspaper article when we lived there (now ten-plus years ago)."
She then began to read from Wikipedia, I think: Gadson made his acting debut in Battleship, a 2012 American science fiction naval war film, playing a war veteran who regains his appetite for the fight when Oahu is threatened by an alien attack. Director Peter Berg, having seen news articles about Gadson, decided to cast him as an army officer trying to recover from the loss of his legs. She noted, On May 7, 2007, he lost both his legs to a roadside bomb in Baghdad. He became one of the first military personnel to use a next-generation powered prosthetic knee with technology to make it possible for amputees to walk with confidence and with a more natural gait. She then zipped through his many awards, including three Bronze Stars, tabulated at the Wikipedia link. He was involved in everything from Bosnia to Iraq.
Several of the recent NCIS - Los Angeles episodes of late have been tiresome, but this one featured a recent Afghani immigrant woman trying to break out of the traditional arranged marriage. Her relations in Afghanistan felt honor-bound to make her keep their commitment to marry someone she'd never met. The double-amputee, portrayed by Gadson, was just a sidebar, but worthy of mention here, I thought.
Never fear - the bad dudes were terminated and love triumphed!
