Jack Coughlin is a joke who fabricated all that crap. It may be a good story, but so "Robinson Crusoe". If you beg to differ, I'd love to put you in touch with my Marksmanship Instructor from the Camp Pendleton course. He's made a personal mission of de-bunking that book
Touching upon a very intense source of personal irritation of mine, the same is true of Jarhead. If you ever want to listen to me cuss at extreme volume, bring up that POS movie/book/author. Bluntly put, I knew "Swoff" and "Swoff" is a bald-faced liar. Of course, anyone who was in the military in general and in the USMC in particular can see through his lies pretty quickly.
On the sniper front, it's a combination of things. Training, fieldcraft, marksmanship above and beyond the standard, mindset and attitude. Technically, if your a Marine, it means that you have passed the required training and are given the MOS designation 8541 (Scout Sniper). Really, it's a job that has been very highly dramaticized in recent years. I think a lot of people are under the impression that it is a very exciting and cool job, full of adventure and danger, but the reality is something different. The reality is that you spend inordinate amounts of time doing pretty much nothing but looking around and searching for targets, followed by a very brief period of action when you pull the trigger, followed by more looking around and searching for targets. Look, read the Carlos Hathcock book "Marine Sniper: 93 confirmed kills". It's interesting and neat and a must-read for any real gunny, but in the end his story boils down to long periods of discomfort and fighting off boredom, broken up by the occasional shot.
Now, let me make it clear that I am not disparaging snipers. Tactically, snipers are an intensely valuable asset, as has been proven time and again in the recent war on terror. I most certainly am not disparaging Carlos Hathcock, who really is a pretty revered figure in the Marine Corps. I am simply saying that it just isn't as exciting as people seem to think it is, most of the time.
Rifleman1973, your post was very nice, and accurate. I would simply point out that many of the skills that you said a sniper must have, so too must the average infantryman.
