Abstract: The barbed nail characteristics, combat boot characteristics, biological contrastive test and hominine foot equivalent research are carried out for stabbing effect test and assessment. An equivalent hominine foot target is developed, of which soft tissues and bone structure are made of silicone rubber and epoxy. The target is made according to the "standard man"dimension and booted with a pair of special homebred combat boots. A stabbing effect evaluation model was established by using the stabbing position, depth, quantity and remaining things of the barbed nails stabbing into hominine foot as the input data based on the biological test, equivalent test and war injuries data. In the model, the degree of impact on operations is divided into levels 1-4 from low to high.The effect of the barbed nail on personnel mobility could be assessed by using the effect assessment model and the test data of the equivalent targets.
