The Information Operations Vulnerability/Survivability Assessment (IOVSA) process, developed by the S urvivability/Lethality Analysis Directorate (SLAD) of the U.S. Army Research Laboratory (ARL) for the purpose of conducting an analysis of the effects of information operations/information warfare (10/lw) threats on battlefield information systems was applied to the M7 model of the Bradley Fire Support Team Vehicle (BFIST). The IOVSA process consists of five distinct phases which must be completed for a complete analysis of 10/lW threat impact on weapon system capability: (1) system familiarization, (2) system design analysis, (3) threat definition and susceptibility assessment, (4) vulnerability risk assessment, and (5) protection assessment and recommendations. This report documents the IOVSA system familiarization phase for the M7 BFIST with particular focus on those critical information systems relating to battlefield communications.
