If you don't want a career, then by all means get out, but it seems to me like they gave a full ride to a dude who never really was fully invested in the Army even while he was in.

Maybe, maybe not. Infantry knowledge is pretty tribal, at least from what I've seen; all that flair on your uniform is awesome, but most of the stuff that's worth knowing was around long before we invented those schools (and gets passed around, in and out of them).

The third week was spent in preparing and conducting an actual instructor-led combat patrol in the mountainous jungle between the massive naval air bases at Nha Trang and Cam Ranh Bay where the enemy often took position to mortar each base. During this patrol each team member switched positions to learn all responsibilities and were graded by the instructor. Graduates of this school received the MACV Recondo patch and identification number.

When I think about how I'd do things, were someone crazy enough to put me in any position of responsibility... I'd follow Westmoreland's example, and cook them on high heat after making sure I'd weeded out the non-hackers...

Just me, but people changed in combat, and the difference was pretty obvious. Some were stacked, others not at all, and you could never tell who'd stand tall... versus the ones who'd slither everywhere.
