Some quite interesting concepts being explored in these articles. Perhaps there are some good ideas here. But as newer gun concepts are explored, I would always keep asking two key questions: 1) How much will any of the gosh darn things weigh, to include the ammunition, batteries, etc., that the average grunt will need to lug around? 2) Will any of these new gee whiz guns, marvelously capable and all, actually withstand the punishment that the average grunt can and will visit upon them in a field environment? During actual combat conditions of dusty, rainy, muddy, etc? If we keep breaking them, what good are they?
I sure hope sane and common sense minds within the grunt community, good Army soldiers and Marines and Navy SEALs all, will keep asking those questions at every stage. Oftentimes, those questions and the uncomfortable answers, seem to be set aside.
