Abstract: Soil-filled barriers, normally filled with heavy equipment, can be made quickly effective against small arms fire by modifying each cell of a barrier line (wall) with internal closeable gates that allow users to manually shovel fill a small arms security position in 65% less time than manually filling a standard barrier. Select embodiments of the present invention include gates that are inexpensive and lightweight compared to alternatives and readily fielded, in some instances as a field expedient modification. In select embodiments of the present invention the gates may be integrated into fielded conventional barriers, including employing field expedient means, as well as incorporated into production lines of new barriers specifically for use by light military units that operate in restrictive terrain.
