Do you guys use smoke greneades?[Discussion]

As titles says, do you use smokes?

are they useful or not?

i just went factory and killed a scav with smoke, someone wanted to push me so i smoked and camped inside and killed him lol

got me thinking how useful are they really.

do they improve strength if i throw them?

is there a difference between the prappor smokes and the american smokes? (i dont have them but saw them)

thanks im kinda noob
