Abstract : A procedure is presented for the selection and description of reference test areas (RTA's) in which the Quadripartite nations can test and evaluate their military vehicles. The procedure consists of four phases: (a) Selection of areas of national interest by each of the Quadripartite nations. (b) Identification and description of the facets comprising the areas of national interest. (c) Selection of RTA's within each member nation in a location which exhibits the maximum number of facet types as found in the areas of national interest. (d) Description of all RTA's in terms of landscape pattern, facet and subfacet composition, factor value ranges characterizing each facet and subfacet, and factor values mapped independently. The factor value descriptions must be in terms of ranges of values for those factors which significantly affect vehicle performance. The factors are hypothesized to be: (a) Soil factors: soil mass strength, soil surface strength. (b) Vertical obstacles: macroslope, step height, width, length, spacing, approach angle, soil mass strength. (c) Lateral obstacles: spacing, stem spread, branching height, clustering index. (d) Longitudinal obstacles: spacing, stem diameter, bending strength, clustering, soil mass strength. (e) Water-land interface: depth, approach angle, current velocity.
