Horizontal Construction Engineers (MOS 12N) are the “grunts” of the U.S. Army.
An Army Horizontal Construction Engineer uses heavy equipment like bulldozers, graders, and cranes to move earth and material in order to complete construction projects for the U.S. Army.
As a result, MOS 12N are delegated with operating a variety of heavy equipment and need to know how the machinery functions as well as maintain the equipment.

Heavy Equipment Operators
The first responsibility and primary duty of an Army Horizontal Construction Engineer (MOS 12N) is simply to move earth.
Heavy equipment operators handle countless types of machines. These include machinery like excavators, backhoes, bulldozers, graders, loaders, trenchers, and scrapers.
The job is to clear, grub, strip, excavate, backfill, stockpile, or push scrape soil with the most appropriate type of machinery for the task at hand.
There is also a need to level earth for other construction projects.
The more knowledge you have with heavy equipment and the more types of machinery you can operate, the better.
Army Construction Projects
The U.S. Army is no different from any organization in that it needs things constructed, sometimes on tight deadlines.
Army Horizontal Construction Engineers work with other team members to see that projects are completed on time, and correctly.
There is a need to analyze the information on grade stakes and also know how to place them.
Depending on your military rank, you may also lead certain construction projects.

Combat Engineer Missions
Army Horizontal Construction Engineers are sometimes delegated to combat engineer missions.
It is possible to get caught in the middle of action while building fighting positions, fortifications, or roads.
The role is extremely important, as combat forces depend on safe roads to travel so MOS 12N can make the process much easier for soldiers.
What does an Army Horizontal Construction Engineer make?
The U.S. Army pays similarly regardless of Military Occupation Specialty (MOS).
Pay is more determined based on Army rank and years of service (see table, below).
However, you can earn extra cash (up to $40,000) for getting assigned to specific jobs that are in demand.
