Combat effectiveness is the capacity or performance of a military force to succeed in undertaking an operation, mission or objective. Determining optimal combat effectiveness is crucial in the armed forces, whether they are deployed on land, air or sea. Combat effectiveness is an aspect of military effectiveness and can be attributed to the strength of combat support including the quality and quantity of logistics, weapons and equipment as well as military tactics, the psychological states of soldiers, level of influence of leaders, skill and motivation that can arise from nationalism to survival are all capable of contributing to success on the battlefield. Combat effectiveness is a function of these factors. Overall combat effectiveness or combat power is the product of a forces strength and the combat effectiveness of that force. Combat effectiveness explains how a numerically weak force can prevail over another that is much stronger. It also explains how relatively small units can have a significant impact on the outcome of a conflict.
== Quantitative measures == Philip Hayward proposes a measure for combat effectiveness, concentrating on the "probability of success" in a combat environment in relation to factors such as manpower and military stratagem. Combat effectiveness can be represented as a real and continuous function,
F
(
x
)
≧
F
(
y
)
{\displaystyle F(x)\geqq F(y)}
where
x
{\displaystyle x}
and
y
{\displaystyle y}
are two distinct military units. He analyses the measure against three main factors: capabilities—the quality and quantity of human and material resources of both friendly and enemy forces; environment—weather and terrain; and missions—region to hold in the specified objective and the latest time to do it while minimising the costs of achieving the objective. Hayward defines
P
(
S
)
¯
{\displaystyle {\bar {P(S)}}}
to be the average probability of success in combat, summarised as
P
(
S
)
¯
=
∫
f
(
x
,
z
)
p
(
z
)
d
z
=
G
(
x
)
{\displaystyle {\bar {P(S)}}=\int f(x,z)p(z)dz=G(x)}
where
x
{\displaystyle x}
is the capabilities of friendly forces,
z
{\displaystyle z}
is the other factors, and
p
(
z
)
{\displaystyle p(z)}
is the probability of situation
z
{\displaystyle z}
occurring in combat. Another measure for combat effectiveness is developed by Youngwoo Lee and Taesik Lee who use a "meta-network representation" approach with regards to the opportunities available for military units to make an attack. The number of enemy casualties is one of the main indicators of success in combat and was used by the United States army in the Vietnam and Korean wars. According to Lee and Lee, there are two types of direct engagements with enemy forces in the network model: isolated attacks and coordinated attacks. Let
A
1
{\displaystyle A_{1}}
and
A
2
{\displaystyle A_{2}}
be two friendly force units and
B
{\displaystyle B}
be an enemy unit. In an isolated attack between
A
1
{\displaystyle A_{1}}
and
B
{\displaystyle B}
,
A
1
{\displaystyle A_{1}}
must carry out the responsibility of both detecting and advancing on
B
{\displaystyle B}
. On the other hand, a coordinated attack allows
A
2
{\displaystyle A_{2}}
to communicate the detection of
B
{\displaystyle B}
to
A
1
{\displaystyle A_{1}}
if
A
1
{\displaystyle A_{1}}
does not have the capability or is not in a position to detect
B
{\displaystyle B}
. If
A
1
{\displaystyle A_{1}}
is in a position to engage
B
{\displaystyle B}
,
A
1
{\displaystyle A_{1}}
may carry out the attack through the organisation between the two friendly forces. Lee and Lee say that more complex combat situations can see these networks expand to include more combat units, locations, capabilities and actions, but the base structure is of an isolated or coordinated attack structure. The larger the network, the greater chance of opportunities for offensive action to become available.
