I can tell you that the surveys are almost always guaranteed to be biased. US service members have the M16/M4 shoved down their throat and get almost no exposure to any other individual weapon systems. Yeah the M4 is the best rifle they have ever used... but the thing is they have never ever held another rifle. For instance, one of my buddies went to the Ukraine with his unit for training with the Ukrainian military. While he was over their, he was able to use a G36. His and his entire unit's opinion changed towards the M4 after using a G36.



By the way, an 18B is a special forces weapons sergeant if you didn't know. They are trained to be experts in using and maintaining a plethora of weapon systems, both foreign and domestic.
