For regular fun times or open terrain maybe, but small arms FA has its use in the dense foliage and vegetation of a jungle environment. When rounds start coming in the effective fire going out should be an immediate and overwhelming response.
Not to mention the rate of fire available from even a handful of guys on FA to dominate and overwhelm a kill zone when the ambush bell rings. I think it’s just a learned discipline to know when it’s going to be effective or when guys are just dumping supplies in an unwarranted fashion.
I suppose?
But I was mostly talking about civilians. Now that I am one? I can't think of any reason why FA would do me any real good at all.
