It's OSUT and for combat arms only.
Our drill sergeants woke us up one day and announced we'd been in AIT for three days, lets all celebrate by doing push ups til someone pukes
Huh?

What is OSUT? And by combat arms your talking bout 11B stuff right? I been out too long, lol.
OSUT "ONE STATION UNIT TRAINING"
15U used to be 67U and when some fly boys decided that since they get shot at or shot down during an infill or exfill, they decided to appeal to the dod to classify avn as a combat arms, since every mos below the 20s is considered a combat arms, 15U is now a combat arms. it was redesignated 15U in 2003, my original mos was 67U, but before I left ft useless, it had been changed to 15U.
heck you got the Infantry and then you got support

y'all don't get to upset with that last comment
I but the grunt like it when they get the support when they ask for it. arty, a support unit, "11 bang-bang is under heavy fire, grunt calls for fire and adjusts fire to help support his ass through the fire fight. 11 bang-bang needs to get somewhere real fast or needs to get out real fast, the grunt calls for a ride, a whirly bird comes in and supports his ass out of harms way" everything else is support huhhhh? just messin with ya ba-iv, we all had a choice, and I chose not to sleep with my head in the mud, and beg for a ride or need some id fire.
