U09031-3 - Army Air Defense Artillery Command (ARADCOM)
This patch became obsolete prior to 1989.
I believe this was used by the Nike anti-ballistic missile units among others. It has a merrowed edge (mid 1970's or later). The patch in the photograph is sold, but I have found a few more examples. I have both the merrowed edge patch used after about 1973 and the cut edge patch used until about 1973. The cut edge patch is used.
