Want to sound like a business in the know? Then talk the talk. Beginning today, Fort Lewis, the Post, McChord Air Force Base — none of these exist.
It's now Joint Base Lewis-McChord. When describing it as a whole, refer to it as the Joint Base or the Base. It's no longer a Post.
McChord is a Field now, which was true 50 years ago before it was an Air Force Base. The correct term is JBLM-McChord Field.
It will take time.
As for us, we are changing the Ranger to The Ranger, dropping off Fort Lewis from our name. From 1951 to 1990, we were known as just The Ranger.
