He's a major which means he's been in the Air Force for at least 7 years, probably longer since major is the first rank for which you have to be selected instead of just promoted to by time in service. That means he was at least 7 years towards his pension, which he would have gotten at 20 years. And I see you're still a f**kin' moron.
He violated AFI 51-508 which expressly forbids the wearing of the Air Force uniform at political rallies or events. That is a lawful regulation, and his violation of that regulation will result in his being charged with Violation of Article 92, Uniform Code of Military Justice, which is "Failure to Obey A Lawful Order or Regulation." And yeah, his career is over.
Are you really that f**kin' stupid? Parades aren't held in neighborhoods, moron, they're held in communites, towns, cities, and such. And I know for a fact that they took place because I was personally in two of them last weekend.
