I don't see it as trying to invoke SCRA, but you indicate it is fraudulent and that is simply a lie. It is telling the collector not just that person is not here, but that they are serving our country. When that is not true, if that creditor does provide special remedies, you are getting those off false pretenses. I don't know that it is illegal, but it is immoral. Not being able to pay a bill is not a crime, nor is it immoral. Personally I think it is worse than just saying we can't do anything, lets make some realistic payment arrangements so you don't have to call.
