Combat engineer organization
Combat engineers play a key role in all armed forces of the world. They are invariably found closely integrated into the force structure of divisions, combat brigades, and smaller fighting units.
Combat support formations
In many countries, combat engineers provide
combat support members of a broader military engineering corps or branch. Other nations have distinct combat engineering corps or branches; they are separate from other types of military engineers. The Danish military engineers' corps, for example, is almost entirely organized into one regiment of combat engineers, simply named
Ingeniørregimentet ("The Engineering Regiment").

Practices and techniques
Combat engineers are force multipliers and enhance the survival of other troops through the use and practice of camouflage, reconnaissance, communications and other services. These include the construction of roads, bridges,
field fortifications, obstacles and the construction and running of water points. In these roles, combat engineers use a wide variety of hand and power tools. They are also responsible for construction rigging, the use of
