i got the sav 20.12.48 when i could but i have a hard time playing it so i would like to know how
Carry mostly APHE and a few HE. Use your speed to get a flank.
The gun should have no problem one shotting whatever you pen and only stuff like the kv1 should give you trouble.
The important thing is to keep in kind the ready rack. Do not spam fire it if you dont have to and make sure you have a place to pull back to wait for it to refill.
thanks should it be the first tank i use in a match
Depends on who you are facing. Normally most players take their best tank, usually a medium or heavy. Understand your BR you are playing, who your enemy is then play accordingly.
i find rushing bt-42 (a 1.7) works i can get a cuopol of kills (in 3.7) with it
It depends. Maybe not for facing Russia due to the kv1.
But i find good success in first spawning it.
