Abstract

The aim of this study was to develop a method including the vulnerability analysis program AVAL to create target descriptions for the training system BT46. The study also included an evaluation of the existing target vulnerability description of "Pansarterrängbil 203" compared to the one developed in AVAL. Target vulnerability descriptions used in BT46 today are developed using the software PTM. The target is divided into areas where the vulnerability probability is computed from the assumed protective armour thickness and the location of vital parts in the area. The vulnerability data from AVAL simulations were believed to be more detailed and correct descriptions of the target vulnerability than those used today. This study compared the AVAL and PTM vulnerability descriptions by recalculating the detailed values from AVAL to mean values covering the areas defined in the BT46 system. The results showed that AVAL and PTM give very different vulnerability values for all of the ammunitions included in the study. Generally, the PTM values were higher than those calculated by AVAL. This was probably due to that PTM considers a perforating penetrator as a kill whereas in AVAL it counts as a kill only if a vital part is hit.
