I found this site a while back and it has a lot of different Military Training manuals there. I just noticed there is one on Sniper Training with some good info on range estimation, weather, temperature and trigger and breath control. It's pretty basic, but may help others who are self taught or if you just like to read.

The main site is here. Good info for survival and such.
