I came accross the following information (quick translation from my side):

3 Su-22s from Swidwin are on exercise Spring Storm 13 in Amari, Estonia, from 15-24May13 for CAS and Air Interdiction.
At the same time 3 Su-22s have deployed to Czech Republic for a COMAO exercise as preparation for the exercise Ramstein Rover this autumn (October).
These two exercises form the most important foreign exercises for the Swidwin based Su-22 unit.
