I spent some significant time with a couple guys from the Israeli military who were part of their most elite units with significant combat experience (and unlike all the other “elite Israeli Commandos” were VERY secretive about what they did or their status). We had a good discussion on some of this. In the case of the Galil, he lived the SAR and his unit used them extensively, especially in the desert and during cross border operations. With that said, when it came to working urban operations and much of their other tasks, they loved the light weight and fast handling of the telescoping stocked short M16 based guns. The reality I found is like most, these folks want a tool. It needs to be easily supported and easy to use and to keep running. I had a good friend sum this up well. When out of country by himself and unsupported by any US logistics chain, he used AK’s. When supported by a US logistics chain, the right tool was a Colt M16 based carbine.
There is a place for bullpups, and a place for M16 based guns, and they will not be the same place.
