There are lots of military farewell traditions that are not "official" that we do- plaques, spurs in the cavalry, framed guidons, you name it. If you leave a unit or retire in good standing, you got the "standard package" of farewell mementos- period. In this unit, spouses got a certificate signed by the commander. Just because it was not official does not mean it was not obligatory. It is wrong for a commander to pick and choose who gets what, based on religious beliefs or anything else. That is favoritism, and favoritism destroys unit morale.
