I've done alot of searching for information on this MOS, but I really haven't found much. Any I was wondering what life in this particular mos is like day to day and where is it possible to get stationed? Are there restrictions or can you get stationed just about anywhere?

On active duty, you can be stationed at:
Fort Leonard Wood, MO
Fort Hood, TX
Fort Polk, LA
Fort Benning, GA
Germany, but I have heard they are moving those units stateside.

I can't tell you the day to day since I am in a Reserve Multi Role Bridge Company. You do OSUT with the Combat Engineers, and do get to play with explosives though. We had one 21C get assigned to Fort Lewis, but there is not a bridging company there....I think they plan to reroute him to another unit shortly.
