Depends , when i played I had basically a 3-2 man Squad. In the specific situation im going to explain there where 3 teammates pinned down behind cover by around 6/8 of the enemy team or around 10 ppl. 1 of my teammates served as a kind of marksman (operator 3) and 2 as strike force(operator1/2) (including me operator 1). The Marksman gave us cover shooting towards the side of their positions, shifting the fortifications to that side. Then Operator 2 rushed the front side of their formation relieving stress of the pinned teammates having their fortifications set to the front and right side (left was a wall). Then I rushed in fast from the back and took them offguard surrounding them and forcing them to repossition . That gave me 2000 points in 1.5 minutes. At the end Aim , Tactics , Versitility and knowing of your surroundings .
Certain special targets are at some fields that are called “field nukes.” If you hit one make sure it’s from a distance because anyone near it gets their vests de-activated for 30 seconds to a minute
