What are “Squad Perks?”

battlefield-3

The answer to this question stated that there are "squad perks" that affect your entire squad, but left a lot of questions unanswered:

  • What do each of these perks do? (I haven't unlocked all the individual perks yet)
  • At what levels do these perks unlock?
  • Do these stack with the individual perks?
  • Do you have to be squad leader for your squad-mates to get the perk? What if a member of the squad has a squad-perk but the squad-leader doesn't?
  • How effective are the squad-perks compared to the individual-perks?

Best Answer

Squad perks are perks that span across all of the members in a squad.

  1. Squad SPRINT(Rank 23) - Makes you and your squad run faster. (+10%)

    Squad AMMO(Rank 26) - Lets you and your squad hold more ammo clips. (2x's as much)

    Squad FLAK (Rank 29) - Gives you and your squad more armor from explosive damage. (-10%)

    Squad EXPL (Rank 31) - Gives you and your squad more rocket ammo, C4, and mines. (2x's as much)

    Squad SUPR ( Rank 33) - Makes you and your squads bullets have more of a suppressive effect. (+50%)

    Squad COVR (Rank 35) - Makes you an your squad more immune to suppressive fire. (-33%)

    Squad FRAG (Rank 37) - Gives you and your squad more grenades. (1)

  2. No they do not stack with individual perks, plan your squad accordingly.

  3. No you do not have to be a squad leader for the perks to work for the squad. The leader does not have to have a squad perk if he doesn't want to, it doesn't matter.

  4. The squad perks are very effective, they are essentially the individual perks but span across your whole squad. Once you have them you can no longer access the regular version of the perk.
