Snipers have their own training program, in all branches. For a sniper serving in a special operations unit, such as the Army Rangers or Special Forces, Marine MARSOC, Navy SEALs, et. al, they will also have to undergo that training, as well.
There are four 15-man Marine Special Operations Teams (MSOTs) within an Marine Special Operations Company (MSOC). In turn, there are four MSOCs within a Marine Special Operations Battalion (MSOB), and right now, there are a total of three active MSOBs.

The abilities of each as shooters depends on the individual... whichever one is a better shot is going to be the better shot, no matter what branch they're in. As for Special Forces and Marine Scout Snipers, they're trained in rather different roles. A Marine Scout Sniper would not be trained in everything a Green Beret would be trained in, nor would a Green Beret have the same priorities in training as a Marine Scout Sniper.
Originally Force Recon, they are now known as Marine Corps Special Operations Command (MARSOC).
SEAL sniping is a specialty meaning they don't do it as a full time job. Marine snipers do it 24/7 so i'd go with the corps.
Yes, Special Operations consists of Army Special Forces, Navy Seals, Army Rangers, (Army) Psychological Operations (PSYOP), (Army) Civil Affairs and now Marine Special Operations. There are women with PSYOP and Civil Affairs skill sets so the answer is YES.
The United States Air Force (USAF) doesn't have "snipers." The USAF trains their members in a Countersniper school. They aren't trained in the same tactical employment role as the Army snipers or the Marine MOS snipers.
MARSOC stands for the United States Marine Corps Forces Special Operations Command. This group is the Marines' contribution to SOCOM special operations. Special Operations forces have been involved in operations around the world including the invasion of Panama, Somalia and the War on Terror.
