A model that simulates combat vehicle cross country mobility on unfrozen peatland has been developed. Two bogs in the north of Sweden have been extensively investigated. Bog depth has been measured with georadar and ground vegetation and soil type have been mapped. Information about the terrain is digitized into a Geographical Information System. In order to be able to correct and adjust the model against reality, several tracked combat vehicles were driven across the bog. Statistical analysis of the results showed that bog vegetation was the major influential terrain factor on trafficability. The investigated vehicle parameter best explaining test vehicle performance is Mean Maximum Pressure (MMP). Bog depth has no obvious influence on neither bog vegetation or test results i.e. sinkage, speed and number of passes. The model gives an interval of the number of passes a specified vehicle can make over a specified bog type with 80% probability.
