USSR BMP2 & BMP3 Autocannon/Cannon Firing on Xbox

[Crashing69R]

First time posting, hopefully I’m doing it right.

I play on Xbox and am using the BMP 2 and 3. I’ve noticed the BMP2 can fire ATGM with Left bumper+right trigger. But with the BMP3 I have to manually switch weaponry systems to fire ATGMs.

Do I have a bad control setup or is this typical?

Included photos as well.

Thanks for any help!

Answered my own question. I went deeper into the “controls” settings that’s separate from “ground vehicle settings.” I took the button for smokes off which was assigned to clicking right stick and switched it to secondary weapon.

Looking forward to seeing how this helps with my other vehicles.
