12y in 1st cav

Hey i havent had luck in the weekly post, so ima ask here. Im a 12y, Geospatial engineer, and i recently got my first duty station. Fort hood, 1st cav 2nd bergade, I was wondering if theres any 12y's here that have either worked under 1st cav or know someone who has, im just wondering what to expect. Since my class mate is going to the III corps in fort hood and I was told its completely different in terms of work than to what I will be doing.
