I was in an NG medical unit---a MASH unit of all things---but it was 30 years ago. The thing about being in a medical unit is that you will probably find that your living conditions are one heck of a lot better than in other Army units----when on active duty you'll typically be clean and dry and warm----you'll have good food, a good place to sleep, etc. My experience, too, was that there was quite a bit less of the "spit and polish" and "gung-ho attitude" in a medical unit, as compared with other Army units. That said, my experiences were, as indicated, 30 years ago----my impression is that quite a bit more is expected of members of the ER/NG today, as compared to when I was in. Heck, when I was in, they were just happy if we showed up on time, stayed somewhat sober and didn't get into too much trouble.
