That is a really nice patch for being in theater made, as some were. However, they also made really funny and crude ones. Here is a picture of some of mine from Vietnam for the 101st that I had in my old airborne collection. The first row are US made, but can easily tell the theater made ones in the 2nd and 3rd rows. Those three were called
The Choking Chicken" patch.
The last few were 82nd patches made for their counterparts in the 101st.
