Abstract
Two witness pack configurations are widely used by The Technical Cooperation Program (TTCP) members to record behind armour debris: the all-steel pack and an aluminium-steel pack. Ballistic impacts were performed for a given shaped charge threat against a specific target to analyse the difference in the behind-armour debris measured using the two different witness packs. This report showed a higher number of fragments recorded and a higher level of incapacitation measured using the aluminium-steel witness pack. The first witness pack layers of the aluminium-steel witness pack are more easily perforated by fragments since they are made of 1 mm of aluminium compared to 0.8 mm of steel for the all-steel pack. Based on this report, it is recommended continuing using the aluminium-steel witness pack for behind-armour debris measurement of a shaped charge impact on a metallic target.
