umm im pretty sure ur not aloud to use tact knife bro....

and the same as P2P bro =)

.... i copied that from the MW2 rules dude so there is nothing about not using tac knifes

ive asked people thats been playing for a while man and ive been playing for a while we never used or were allowed too unless they recently changed it

yep they could of but not since ive been a member of cg cuz i read the rules when i got on ah well everyone makes mistakes

archie

not sure
but M16 ftw
on all cods

thanks to everyone for your advise and feedback
Cheers

thanks every1 for your help

Just want to add that i would use either the scar with fmj for accuracy or the tar21 for fire rate and power. Secondary would be the magnum with fmj due to it power aswell as fire rate.

Also just noticed that you didnt ask but i would also use flashbangs because you get hitmarkers so you will know that a person is there and have frag grenade because they better then throwing knife.
