  This article presents empirical models for the relationship between peak
ballistic pressure wave magnitude and incapacitation times in the Strasbourg
goat test data. Using a model with the expected limiting behavior at large and
small pressure wave magnitudes, the average incapacitation times are highly
correlated (R = 0.91) with peak pressure wave magnitude. The cumulative
incapacitation probability as a function of time reveals both fast (t < 5 s)
and slow (t > 5 s) incapacitation mechanisms. The fast incapacitation mechanism
can be accurately modeled as a function of peak pressure wave magnitude. The
slow incapacitation mechanism is presumably due to blood loss via damaged
vascular tissue.
