Sometimes known as "fork and knife school". I can't speak specifically for the Army, but a particular personal incident comes to mind.
When I attended AFROTC field training at Maxwell AFB, in a lot of ways it was a fairly typical boot camp experience, with roaming enlisted training instructors ready to very promptly and firmly correct any deviations from standard in a memorably expedient fashion (much less swearing than Full Metal Jacket, as it's the Air Force). One day during this fine summer camp I found myself on the receiving end of one such chewing out from a TI, for walking around the wrong side of a table in the dining facility.
It was in the midst of this comically scathing tirade (something about him threatening to crawl up my nose and living in my nightmares if I dared try it again) that this Technical Sergeant abruptly stopped, wheeled around and was about to tear into another hapless cadet that took the same detour I did. But instead, without a whit of the seething rage he was pouring out just a second before, he calmly patiently explained to this trainee that she was to take a different route, punctuating the instructions with a "right over there, ma'am". It was at that moment that I noticed that she did not have cadet insignia on her lapels, but captain's bars. It turns out she was a proper M.D., fresh from med school, directly commissioned and immediately outranking the sergeant that was giving me the what-for and her polite guidance.
So by Direct Commissioning, it is indeed direct.
