Are there different expectations for E4's in OSUT?

Everyone wears their rank in basic. And you can mention your college degree. The thing is military experience. Sure, you may be a little more experienced in life than some, but infantry knowledge you know as much as they do. No higher expectations will be put on you, unless you prove to the DS that you can handle responsibility. Now having been through more schooling you might be able to learn faster and retain more information than your run of the mill 18 year old. Good luck in basic. When you get there, 30th AG, the reception battalion, is the worst thing you'll ever experience. So when you're sitting out in the rain in a foxhole during your FTX, you can remember at least your not at 30th AG. Hahaha. But seriously, good luck.
