Which SAM system is used in each sim bracket?

What SAMs are used at airbases and what are their effective ranges? How high can one fly to avoid them?

I’m not sure at which BRs the AA switches at, but at lower tiers, it just gets flak guns with an effective range of probably about 3km, but only really effective point blank against someone who is aware and not flying in a straight line. Mid tiers get veaks, strelas, and roland 1s, max range of 6.5km for the roland 1 and not really too hard to dodge. High tier (not really 100% sure on this one) I think just replaces the roland 1 with ITO-90, with a max range of 12km.
