If you are Airborne 101st division in the army does that mean you must be infantry?

Question

or can you be in human resources and still be airborne and why is there different airborne patches?? i have seen the eagle,,the sword and two AA that say airborne....What exactly does that mean?? How do you get into divisions? whats that all about??

Answer 1

 The guy below me said it perfectly. 101st is air mobile or air assault and had the highest death rate in Iraq.

more MOS are allowed but harder to get in. 

Diff insignias for diff units

Screaming Eagle- 101st

AA-82nd
