Not necessarily. If you wish to become a military sniper, you'll have to be in the military already, of course. If you want to be a sniper in something outside the military, such as law enforcement or some backwoods militia, then no.
Join the army
A medical condition such as that would disqualify you for enlistment, let alone becoming a sniper.

Well, first, you should ensure you can make it. You won't enlist into the Army or the Navy as a sniper - in the Army, you'd have to enlist as either an infantryman or Cavalry Scout, then request and be accepted for the Army's sniper course. IIRC, the only way to become a sniper in the Navy is by first becoming a SEAL. If you feel up to that challenge, by all means, go for it. I can't say with any certainty, but I believe you can enlist into the Marines for the Scout Sniper MOS. However, you still must pass the course before actually becoming a Scout Sniper. One thing you need to keep in mind is that there's a lot more to being a sniper than simply being a good shot. As for which one to choose, you need to decide what's best for you. -Bryce- Marine snipers are known for their best shot. Before you go in, you should know the basics on range cards, field sketches, moving silently in thick foilage, and other things. Knowing how to shoot a sniper (any BOLT-action rifle that can shoot past 250 yards, or a semi-auto rifle that could also shoot past 250 yards) rifle wouldn't hurt, either. Wish you the best of luck, and the choice is yours.
http://science.howstuffworks.com/sniper.htm This website tells you how military snipers work :) I'm no sniper myself, but I have been to the army. All soldiers go through Basic Millitary Training (for my country) before being posted to a vocation (such as sniper). In which they will receive further more specialised training.

US Army Sniper School is five weeks long at Ft. Benning, Georgia.
Sniper is an Army and Marine MOS. It is not related to rank or paygrade.
None VERY VERY few, because Navy SEAL snipers are always hidden. Even when they move, they are either in gillie suites or they move when no one is around or by the shadows, Navy SEAL snipers never get compromised unless they miss, which is almost never.
