Computing Kill Probability
PK = PH * PP * PL * PR
PK = Probability of Kill. Final Probability.
PH = Probability of a Hit. Overall function of range, affected by fire control system.
PP = Probability of a Penetration. Overall function of weapon/ammunition design.
PL = Probability of a penetration inflicting lethal damage. Overall function of weapon/ammunition design.
PR = Reliability of system. Probability of functioning correctly; overall function of the weapons system.
