No.
The Court of Appeals for the Armed Forces (Military Court of Appeals) and the US Supreme Court are in separate chains of authority. The former is a military court (an Article I tribunal), while the latter is a civilian court (and an Article III tribunal). Cases may be appealed from the Court of Appeals for the Armed Forces to the Supreme Court; however, this is a rare occurrence.
In any event, there is no appellate court above the Supreme Court at all.
The Supreme Court historically separates itself from military matters, allowing the military court system to handle military matters as members of the armed forces are not entitled to the same legal protections as civilians. The UCMJ is the military's version of the Constitution so-to-speak.
Also, SCOTUS does not 'try' cases. Rather, the Court hears challenges to the constitutionality of laws and rulings made by lower courts (such as withheld evidence, prosecutor misconduct, etc.) . That's why many criminals who file for writs of certiorari are denied because their cases do not qualify under those parameters.
Because the Supreme Court is constitutionally the highest court in all the land, barring an amendment being passed preventing them from getting involved in military rulings, they could hypothetically overturn a military tribunal.
However, unless there was gross negligence on the part of the military court, it's highly unlikely they would even get involved.
Yes, cases may be appealed to the US Supreme Court from the US Court of Appeals for the Armed Forces (military appellate court).
No it can't. The only way to overturn a supreme court decision is either another supreme court decision, or a constitutional amendment.
By issuing a judicial review.
Sometimes. If the Supreme Court decision interprets a statute or common law, it can be overturned by a legislative statute to the contrary. However, if the Supreme Court decision is interpreting constitutional law, a constitutional amendment would be required to overturn the decision.
The Eighteenth Amendment, which established Prohibition, was not added to overturn a Supreme Court decision. It was added to the Constitution to ban the manufacture, sale, and transportation of alcoholic beverages.
A U. S. president cannot reverse a U. S. Supreme Court decision or the decision of the Supreme Court of any state or territory.

Plessy V Ferguson (1896)
The president does not have any power over the decisions of the Supreme Court. Only the Supreme Court itself can overturn a supreme court decision.
Plessy v. Ferguson (1896),
"Seperate but Equal", from the case Plessy vs. Ferguson.
An appellant may file a motion for a rehearing, if warranted, but the US Supreme Court has full discretion to grant or deny this request. If denied, the case is considered res judicata(completed), and the decision of the Court is both final and binding.
A simple majority can overturn a previous ruling. This is what happened when the current idiots declared corporations "people" for legal purposes and will allow them to buy and sell politicians even more in US elections.
