It is home to The Big Red 1. I guess there are others their too. It’s a big place.
I think, in typical "journalist" fashion, they couldn't get the most basic facts right in their story. I believe the unit they are referring to is the 2nd Battalion, 34th Armor Regiment. I found a story about a soldier from that unit who was KIA in afghanistan in 2011 and that unit was based in Ft. Riley.
