The significance of this is that all of the previous cases that were filed were civilian, civil court cases.

It is a very interesting situation that this officer has put the military in.  Here is my explanation:

1.  The officer swore an oath to defend the Constitution and that is the cornerstone of his military obligation;
2.  The officer is alleging that the Commander in Chief is violating the constitution because President Obama is not a "natural born citizen" of the US as required by the Constitution to hold the office of the President.
3.  The only facts in dispute is whether or not President Obama was born in Kenya as his Kenya relatives are on the record claiming, and that he arrived in Hawaii within a week after his birth where his mother then obtained a birth certificate; or,  if he was actually born at the hospital in Hawaii.  
4.  It is not disputed that President Obama and the State of Hawaii have refused to release the original birth certificate.
5.  It is not not disputed that President Obama's father was not a US Citizen at the time, but was in fact a citizen of the United Kingdom and that the Constitution does not allow the office of the President to be held by a person who's parents were not both US Citizens.
6.  President Obama was adopted by an Indonesian Muslim and that adoption would have provided him Indonesian citizenship and revoked his US Citizenship.
7.  When President Obama returned to Hawaii after his mother's divorce from the Indonesian Muslim, he would have needed to file "re-patriation" papers in which his status as an Indonesian Citizen was terminated and he would then have been "re-patriated" or returned status as an American Citizen.   These immigration records have not been produced.

The dilemma here is that the Military Serviceman is probably legally correct in that President Obama is not legally qualified to hold the office.   But politically, this is an issue that could ignite the Second Civil War.

My belief  is that the military judge, judge advocates and jurors are going to all follow their oath and the law, rather than politics, and that the military court will require the production of documents that so far have not been produced.     If these documents are not produced or if there is any question as to their legitimacy, the officer will be acquitted.   That result would then put the entire chain of command on notice that their own court has determined that President Obama cannot establish his legitimacy to hold office and accordingly the command is under no obligation to follow his orders and many be under a constitutional obligation to remove him from office.

I for one would support a military coup if that is what it took to re-instate a legal, constitutional government and I imagine that there is a significant number of other people who think accordingly.
