Dead Silence not only prevents the enemy team from knowing exactly where you are.. it also does not give away your teammates position if you are near them.
If you are a new player, you can unlock Dead Silence with squad points (not sure how many). So please do so as it's not only helps you but also your team!
Thanks and Happy New Year!
TBH... you can use your loud friend to your advantage.
DS is useful on certain maps in certain situations... but I also like having the other team hear my footsteps echoing like the wrath of God.
