Only if they are used to make people think they are yours without having earned them !! You can still buy ribbons and medals in every DAV magazine !! Read the last sentence in that paragraph !! That was struck down because it violated the first amendment,,freedom of speech !!
So as it stands today,,you can tell people anything you want to but you can not put the medals authorized by congress and present your self as the one who won them !! If you do with the Medal of Honor it can get you a stay in prison !!
