The battery commander can coordinate for additional troops to clear areas of small enemy forces, obstacles, and minefields. Security is continuous throughout advance party operations. Once a location is determined to be safe, the advance party prepares the position for guns. This consists of several procedures, such as escorting each weapon to its prepared position, setting up communications, providing the unit with its initial elevation, and providing each gun with an initial deflection. This entire process is covered in U.S. Army Field Manual 6-50 Chapter 2.
