Objective

• Formulating a descriptive mathematical model

for assessing casualty rates in an Infantry attack

2

Unclassified

Scope

• This study assess casualty rates, in an infantry attack
• n an unfortified stronghold garrisoned by

infantry soldiers as well, caused by two types of fire that can be applied on the battlefield:

• Indirect fire, i.e. artillery of different types
• Direct fire

3

For the purpose of this study direct fire is defined as fire from personal assault weapons that require a direct line

• f sight for engaging targets

Unclassified

Method Overview

• Formulating a descriptive model for describing

a generic infantry attack

• Modeling the connections between activities
• Analysis - Applying to chosen scenarios as

part of the general methodology

Model Assumptions

7

• The basic infantry unit is the Buddy team, it can be

engaged in only one of the activities above at a given time

• The fighting of a team or a squad can be described by the

fighting of it’s Buddy teams

• The battlefield is dynamic and includes several forces the

activities of one side influence the other (casualties, movement times etc)

Unclassified

Method Overview

• Building a descriptive model for describing a

generic infantry attack

• Modeling the connections between the

activities in the model

• Applying to chosen scenarios as part of the

general methodology

Couples of Activities

• Feasible
• Unfeasible/

Unlikely

• These connections exist between different activities

infantry soldiers can be engaged in during combat

The activity couples are modules, they are described using flow charts

Unclassified 10

The activity couples are constructed from sub-activities which are “Functions” described using mathematical tools

Demonstration of Selected Functions

• Firing - computing the hit probabilities
• Objective clearing

Applying the Model – Demonstration

cont.

• “Breaking” the scenario into Buddy teams combat:
• 3 squads offensives = 12 buddy teams combats
• Range to objective from assault position =

200 meters

• Fire rate
• …

Applying the Model – Demonstration

cont.

• Describing each attack (the connections between the sides)

using the modules:

• Using Monte-Carlo simulations to describe the scenario

(MATLAB)

• Extracting the distribution of the casualties from the

simulations

Concluding Remarks

• On Infantry Vulnerability Is one of the building blocks of

the methodology for comparing force configurations based on operational efficiency

• The model gives a thorough description of infantry

combats and supply mathematical tools for assessing different parameters

• The generic modules presented in the study can be used

to describe a variety of scenarios and can be used to evaluate different offered tactics or abilities and their influence
