What should I be working on to be better prepared for Sniper School?

You need to have the fundamentals down, that is for sure, but it isn't all about just shooting. &nbsp;However, I can get a 19D to plink an 800 meter target in under 10 minutes. &nbsp;You need to learn about reading mirage, how to function the scope, learn about minutes of angle (read this&nbsp;http://www.snipercountry.com/articles/mildot_moa.asp), PFC Mullins is correct about angle shooting (but it isn't that difficult a concept if you understand ballistics). &nbsp;<div><br></div><div id="">Then there is the field craft. &nbsp;EVerytime we go to the range everybody and their mother wants to come shoot because it is fun. &nbsp;However, when we go to the field it is a fucking ghost town because no one wants to crawl around in a burlap sack for hours. &nbsp;I highly suggest getting ahold of FM 3-22.10 and give it a thorough reading. &nbsp;If you have any specific questions just PM me.</div><div class="pta-link-card"><div class="pta-link-card-picture"><img src="http://www.snipercountry.com/graphics/mil-dot_reticle.gif"></div><div class="pta-link-card-content"><div class="pta-link-card-title"><a target="_blank" href="http://www.snipercountry.com/articles/mildot_moa.asp">Mil-dots and Minutes-of-angle - From a Technical Perspective</a></div><div class="pta-link-card-description">If you've always wondered what those little dots are for on a military

I think the criteria of sniper school was marksmanship, camouflage and movement and concealment. They are the best shock troops. They often go for days without food, or sleep and must be focused on looking for their target and kill it, yet still avoid enemy troops patrolling the area looking for him. Once the mission is over be capable of escaping and living on for another day.

Range estimation is challenging for a lot of people, and something that you can easily practice just about any moment you want to. It's not a big deal to estimate if somebody is 50m or 100m away, but what about 500m vs 600m? Or 750m vs 850m? That difference can mean hitting your shot or not. While the reticle of a scope will help with that estimation, it's something you can start to build a better intuition for.
