Damn you for giving me exactly what I asked for Yoink!
While not specifically directed at rookie mistakes, this page mentions and sources a wide variety of infantryman-related research and observations.
Paraphrasing (and missing the point): "They don't shoot, if they do shoot they don't hit anything, and if they do hit something they don't duck".
The accuracy-related points are really quite interesting, and gels a little with what my platoon was told during basic training... "Don't worry about hitting anything, we don't expect you to hit anything; that's not what this is about. This is about having more lead in the air flying towards them than towards us".
Hell yeah dude, this has loads of links to interesting and relevant material, this is perfect, thank you!!! Also, you're in the military?
Was. Norwegian military still has a draft of all able-bodied young men (and women now, finally!) to serve in the "national defense" for a year. (note that only about 20% of those who show up for the draft inspection actually "make the grade" and end up serving). ...which, really, is just barely long enough to start learning how to actually do your job, and then you're out.
That's what I did. It's like Baby's First Army, with no risk of deployment or active combat (but also incompetent, inexperienced bureaucratic officers who are barely older than you are. So, pretty standard), except it's north of the arctic circle and about -40 degrees.
The "All I want for Xmas is an HK416" link in my sig is my patchy, opinionated account of the affair.
