about half of snipers in call of duty are mobile snipers.
thats what i do, ive spent months practicing to be able to no scope or quick snipe someone in close range and i have confidence that i can beat any weapon with my sniper.
and with the hb sensor you can tell where people are and you have an element of suprise on them.
i would say im about as good with a sniper as that montage i posted
