In military engineering, earthworks are, more specifically, types of fortifications constructed from soil.

Examples of older earthwork fortifications include moats, sod walls, motte-and-bailey castles, and hill forts.
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt):
Construction of CCS earth retention is simplified as each layer is structurally sound thereby providing access for equipment and workers, while eliminating the need for concrete formwork and curing. Local soil can be used for infill when suitable and granular, while the outer faces enable a green or tan fascia of the horizontal terraces/rows ...
