If you are like all the 21B I know (my hubby is a 21B and I deployed last time with 21B so I know alot of them) You will drive around looking for IEDs to go boom.
I can tell ya for sure THE MOB STATION SUCKS-they try to say "it ain't basic training" but alot of the trainers (O-C-T's) have a nasty attitude.at least the ones in Indiana! So just do your best to get thru the Mobilzation Process and when ya get in country it will be alot better.
