(“the Actsâ€), law enforcement agencies of the United States or of any department or agency thereof,
and law enforcement agencies of any State or any department, agency or political subdivision thereof,

UPS label, requesting an adult signature upon delivery, to each package containing a firearm. Adult

UPS Commercial Counter. Small arms ammunition, as defined in 49 C.F.R. § 173.59, will be
transported only when packaged and labeled in compliance with 49 C.F.R. § 172.
As you can see by this section
