## Computing Kill Probability |

**P**_{K}
**= P**_{H}
*** P**_{P}
*** P**_{L}
*** P**_{R}

Where:

**P**_{K}= Probability of Kill. Final Probability.**P**_{H}= Probability of a Hit. Overall function of range, affected by fire control system.**P**_{P}= Probability of a Penetration. Overall function of weapon/ammunition design.**P**_{L}= Probability of a penetration inflicting lethal damage. Overall function of weapon/ammunition design.**P**_{R}= Reliability of system. Probability of functioning correctly; overall function of the weapons system.
