Serviceable (Yes or No) - ATF 5320.20 Application to Transport NFA Firearms

When you are filling out the ATF Form 20 – 5320.20 Application to Transport NFA Firearms form, there is a question asking if the NFA Firearm is serviceable or not.  The options are, yes it is serviceable or no it isn't serviceable.  What does that question mean though?  This question refers to the working condition of the NFA firearm.  

Serviceable - Yes: The NFA firearm can be operated the way that the NFA firearm was intended to be used. 

Serviceable - No: The NFA firearm cannot be operated the way that the NFA firearm was intended to be used.  Meaning that the NFA firearm is damaged in any way or has been altered and cannot be used the way it was intended to be used.
