55sixer bullets not as strong as 76two bullets.

762 are typical from those YAK russian fighter during WW2 can shred cows to pieces, whereas 556 just do some minor wound only.

to put to simpler words,

Terrorist Wins! - CS:Go

it's preferable to bring automatic weapons rather than semi or bolt action/pump action where you can only shoot one bullet/shell at a time.

if use MP5, hold the trigger or burst fire, can shoot rapid fire, at least one of the bullet shot will hit the perpetrator.

spray & pray.

thank you battlefield 3 / CS:Go!
