Pzr Campaign Disruption Recovery

[Jim]

So I assume Quality rating and Morale rating not to be one and the same. Quality rating doesnt change but Morale rating changes with battlefield circumstances? So in short, does a Quality "A" unit, when disrupted, (no other detriments) roll a "5" to rally from disruption? His current morale value is "B" not "A". If this is the case then there is never a chance that a unit would ever need to roll a "6" to recover from disruption?  Just to be sure.
