That is not an "undecorated Marine", it's a general from the Old Guard in Army dress blues. The Old Guard is in charge of Arlington and most ceremonial functions. He has two gold stripes on his trousers which indicate his rank. The overcoat is seasonal for cold weather and is worn without decoration and the white bib scarf is also ceremonial.
The guy is an Army general, not a Marine, there is an Old Guard Honor Guard tab on his overcoat. Decorations and medals aren't worn on the cold weather overcoat. The pants are the darker blue that the Army wears and only General officers have two gold stripes on their trousers. The officers at Trump's inauguration werent wearing overcoats which is why you could see their medals. You can check AR-670-1 to verify the uniform specs for the Army dress blue uniform.
