APPROVED BY:

Maj. Adam Deitrich

Product Manager, Engineer Systems

1.0 SCOPE

1.1. Scope. This specification prescribes the performance requirements and identifies verification procedures for the Backhoe Loader (BHL). The BHL will provide the Marine Corps with an excavation capability to rapidly dig small sized combat emplacements. The BHL consists of a basic wheeled, engine driven vehicle with backhoe, bucket loader, and the capability to operate hydraulic tools. The fielded system that met the BHL capability requirement and is currently fielded is a commercially produced BHL. The Marine Corps maintains the requirement to dig small sized combat emplacements, trenches, and conduct general engineering tasks which the BHL is well suited to perform. This capability remains doctrinally and conceptually relevant and is necessary to support the engineering function of logistics.

1.1. Requirement Levels. This specification lists two values for certain performance parameters. The threshold (T) is the minimum acceptable level. The objective (O) is the desired level at which performance of the BHL results in an operationally significant increase in capabilities. When only one requirement is stated, it is the threshold requirement.
