In this case, the subunit from the NATO Battalion Battle Group was replaced by the 3rd battalion tactical unit from the12 Mechanized Brigade. Heavy tanks Abrams M1 and infantry vehicles Bradley M2, after leaving the defensive line, started to restore combat capabilities. Their task was taken over by wheeled armoured transporters Rosomak. In order to conduct proper relief in place manoeuvre, forces were covered by the Task Group of the 15 Giżycko Mechanized Brigade.
