The Army Training and Testing Area Carrying Capacity ATTACC program is a methodology for estimating training and testing land carrying capacity. The methodology is used to determine land rehabilitation and maintenance costs associated with land-based training. ATTACC is part of the Armys Integrated Training Area Management ITAM Program. The ATTACC methodology quantifies training load in terms of Maneuver Impact Miles MIM, which are based on vehicle mileage projection. Each vehicle in each training event has a different impact on the land. To account for these differences, all training events are normalized to a standard unit in a standard event. The ATTACC standard is the MlA2 in an armor battalion in a field training exercise FTX. Training impact factors represent the difference in impact between vehicles and events as compared to the standard. The factors used to calculate MIM are Vehicle Severity Factors VSF, Event Severity Factors ESF, Vehicle Conversion Factors VCF, Vehicle Off-Road Factors VOF, and Local Condition Factors LCF. Vehicle Severity Factors account for the differences in impacts due to different types of vehicles. Local Condition Factors account for differences in vehicle impacts due to weather variations. This report documents a methodology for estimating ATTACC vehicle severity factors and local condition factors. The methodology is based on a reanalysis of data and models used in the NATO Reference Mobility Model.
