How are you listening to that?
Not just listening seeing the aircraft activity and reports of movement, etc. you can also check the common frequencies they use on http://websdr.ewi.utwente.nl:8901/ (You can't really just listen in except when they use voice in the clear on 4372KHz or 8090KHz being the most common ones for Russian bombers but even that not very useful unless you know Russian and the codes they use).
