Your pics really envoked some familiar feelings, although my combat time was spend in the desert. Small world moment, my cousin served in the same battalion as you did, but in Germany in the late 80s after they became a Pershing missle unit. I recognized the regimental crest and the shoulder cord. I did 3 years with the 101st myself.
The -47s in your pics are CH-47Bs, and are similar the the CH-47Cs I had the pleasure (and displeasure) of working on. It was a huge leap forward when the CH-47Ds came around, and now I deal with CH-47Fs as a civilian. Time marches on...
