Also about changeing location, do it every 5 kills or so, and definetly change position after you kill a sniper cause they will want to hunt you down.

Some of the more benifitical kills come from killin engis cause they prolly repairing enemy tanks so they are my usual target.

I also try to keep it not zoomed in all the way, about middle zoom is good cause you can hit your target and you can scan for targets better.

Then of coarse is my fav job as sniper, the "assult sniper" if ya got good aim this is really good to use.
