"Back in the day", NCO's and O's automatically qualified for these, and the E-1 thru E-4 had to pass a Cav specific skill qualifications test to wear them. That was before Gen. Rogers banned all special accouterments from army units.
Of course, "Back in the Day", a Cav battalion-size unit was referred to as a "Squadron", and a company sized unit was a "Troop".
Thanks. All spouses, whether they are with their loved ones or not, are doing their time.
This not only honors the spouse, but lets them feel more like a part of the unit, and helps them to understand our warriors disciplines.
