IDA developed a framework and associated analysis for computing the risk of significant injury (RSI) from blunt impact projectiles. This document includes four appendices describing that framework and how to employ it. The Joint Intermediate Force Capabilities Office (JIFCO) desired a way to estimate the RSI for any given projectile/employment combination incorporating such factors as targeting distance, aiming and delivery accuracy, impact velocity, reactive postures, and projectile and tissue properties. JIFCO has access to various models for different aspects of the analysis, however, the current document describes how to employ and combine these models to build the overall risk estimate.
