In response to a guaranteed commission, that is a load of crap.
RTFQ- The original poster was asking about the garunteed MOS contracts (ie the flight contracts)
noone will show you more thouroughly how to be a marine officer than a SNCO. Dont kid yourself, Enlisted marines are the backbone of the marine corps and its their lives your put in charge of so they should be the ones to train you....hence drill instructors at OCS....I came by that conclusion from common sense.
Dude, you aren't even commissioned yet. You have no baseline to gauge what most throughly shows you how to be an officer.
Many people would argue, as you have, that the PLC/OCC experience is just a screening process. The SNCO gets you to the door- once you pin on your bars and walk through it, thats where you start to learn how to be an officer.
Dont for a minute think that your ROTC program is OCS. Im quite sure NROTC is a great experience in which a great deal is learned. OCS wasnt created to teach you military history or terminolgy. Its a screening process.
NROTC is a screening process in itself.
The general consensus here is that youre prospective of the way things work is exceptionally narrow right now, and that you don't really have a clue what you are talking about. Finish school get commissioned and get some exposure before you start handing out career advice. Until then, stick to what you know... and lay off the koolaid.
