you dont really need a ghille suit to be a good sniper but it helps you to blend in with the eviroment around you. they are not to excpencive around £80 up to £200
Step 2: Sniper
of cource you need a decent sniper perconally i use my Warrior l96 awp. there is lots of diferent snipers you can have but if you are a beginner i recomend you to get some sort of a l96 spring powerd 500 fps
Step 3: Side arm
the side arm is either a small compact machine gun or a pistol, i have a 18c burst fire and semi automatic glock. these range from the prices of £20 to £150
Step 4: Ammunition
this depends on the FPS (feet per scond) your gun is. if it is 500 fps like mine i recompent 0.26-0.30 gram. if you have .26 gram you will get more force but less distance but .30 bb's you will get more distance and better accuracy but dont get to high with ammunition or it coud clog up your barrel and nakker it :S
Step 5: Foot wear
your foot wear is important, you need thick durable but light boots and waterproof because you will be crawling on the floow alot of the time in game
Step 6: Spare equipment
you need spare equipment such as spar magazines and bbs and airsoft grenades.
Step 7: Saftey gear
the most improtant part of airsoft is protection. i advise getting a full paint ball mask and fingerless leather gloves... fingerless so you can reload easy. NEVER TAKE OF MASK IN GAME OR SOMETHING BAD MIGHT HAPPEN!!
