Does the 12W MOS translate well in the civilian world?

This varies state to state. Some states this is a licensed activity, other states it isn't. This would be tracking your hours and experience in a way that relates to the state you will seek a license. Some states recognize the Army program of instruction in AIT and subsequent work, some don't. You will need to do some research. If there is a carpentry or masonry union hall near you walk and see what they can tell you.

I work in the Facilities construction and maintenance field. These skills are in high demand in region. Recommend tracking your experience and maintaining contact with former supervisors to sign off on your stuff when you sub,it for a license down the road.

Depends on state. I'm a sgt for 12w and there isn't anything for Illinois cause we're bankrupt haha
