An Airsoft Sniper to me is one who takes advantage every place they can.
These are all places where the Airsoft Sniper should be focusing. Master one or two areas and you will be a good Airsoft Sniper, one who is feared at the field, first picked for teams, and makes a difference in every game they play.
Master all areas and you are a FORCE.
Don't limit yourself with the mindset that you don't need a great gun, or great gear. Money does not equal great in this case either. Describing a gun based on how much it costs is ludicrous, describing it based on what it can do though is accurate and appropriate.
I care as little for the guys that brag about how much their gear costs as I do for guys that try to belittle the players with expensive loadouts. Both are focusing on the cost, albeit for different reasons.
Everything we take into the field, from gear, guns, ammo, mindset, ability level, training, etc can be improved upon and should be improved upon. It is a package deal, don't limit yourself.
