Great to hear that real training is being done to maximize pilot's effectiveness, as well. I understand them sticking with an M4 variant shooting 5.56 for logistical reasons. Do you know why a suppressor wasn't included? I would think it would be important help mask one's location. Was the desire for 500m range deemed more important than might be achievable with the shorter barrel that including a suppressor might require? It looks like a 12.5 inch barrel currently--is that right? What do you think about that trade off?
