Snipers are useless in a walk-on day (well they can be used to scare the s*** out of the new players

)
Snipers were first used to pick out a high ranking officer/NCO and take them out destroying the chain of command and scutteling the orgenization
They are now used to gather information. 90% of there job is noteing down enemy positions, their pattens, there attuide, gear, weapons, chain of command, any dutys etc
Only 10% of the time is shooting and its only if you have a clear shot then is move move move!!
In airsoft Snipers are only truly effective in a Mil-sim situation to gather information
Now spotters help the sniper by relaying information donw the radio back to command, they also carry around a set of binoculars so they have a wider field of view
Spotters can carry rifles but mostly carry SMG's. becuase they need to be as mobile and steathy as possible and lugging around a full sized M4 could prevent that.
Hope this is helpfull
