I leave in August and I'm just wondering what 12T life in the Army is like right now?

Sir,
12T here..
This is a description from goarmy.com..
OVERVIEW
The technical engineer supervises or participates in construction site development in areas such as technical investigation, surveys, drafts and construction plans/specifications. They conduct land surveys, make maps and prepare detailed plans for construction projects.
JOB DUTIES
Perform field and laboratory tests on construction materials, surveys and drafts
Draw topographic maps and charts using Computer Aided Drafting systems and software
Conduct geodetic and construction surveys and results utilizing Automated Integrated Survey Instruments and Global Positioning Survey Technology
Draw diagrams for wiring and plumbing of structures
Provide technical support for vertical and horizontal construction projects
Build scale models of land areas that show hills, lakes, roads and buildings.

Basically we design roads, buildings, airstrips, etc using various drafting software. We will stake out those designs utilizing various surveying equipment (also will survey existing land area), and will also test the soil to ensure it is sturdy enough to be built on.
Other materials we test can include concrete and asphalt to ensure it meets design criteria.

Wow, how times have changed. Back in my day, Battalions had a survey section (Philadelphia rod, transit, etc.). Nowhere near the job description above (to my memory). Slump tests were done by the engineers (combat, or construction) on site. Map making was a separate engineer identifier.

Thanks for the update.

You are welcome, Sir.
Technically it has evolved into 4 MOSs in one now.
