What other roles can the MiG-31BM do?

well not just the MiG-31BM, but also the MiG-31BS and 31M (just these three variants i’m looking at in particular)..

We know that the Foxhoud is capable of intercepting cruise missles and bombers.. but what other roles can these later variants ben used for?

also has all three had their radar “problem” rectified? meaning the leak that got out to the US regarding the Zaslon is no longer a problem for these 3?
