When I was with the CalGuard they were an air assault battalion. I heard that changed, but not sure. Many of the background extras for "We Were Soldiers" came from 1-184.
They were a pretty squared away unit for the Guard back then, but everything is what you make of it.
Their lineage goes all the way back to the "2nd California" Infantry Regiment.
