Untucked is not an option, we wear horsehair sporrans with no pouch so have to wear a summons pouch to carry essentials on our belt, plus some members being firefighters feel the need to carry multiple cell phones, radios and water bottle carriers, so if untucked we look, well, lumpy.
I would say that your band is the exception that proves the rule. Because belts are a requirement in your case, your sweaters wouldn't be worn untucked; they have to be tucked in to facilitate wearing the belts.

Like others, I have a couple of tight sweaters that I wear tucked in; the rest are worn untucked sans belt. If I had a sweater vest (haven't found one at a good price yet), I would wear it untucked without a belt.
