Combat Review: FPE & HPE?

[MarkShot]

What would make one side's engagements in general have much higher FPEs and correspondingly HPEs which then manifest as more DES DAM and DIS elements?

Fatigue?

Experience?

I can see my own values. Flip sides and load a save as the enemy to compare?

Thanks.

It seems like it's basically every multiplier you could think of which is influencing your FPE/HPE values. Altough ammunition stockpile of the Division may have a slightly bigger impact than other multipliers.



Note: I have not checked the Living Manual if there are changes to this.

23.8.1.
[...]
The next step is to determine which ground elements
will be able to fire. There are multiple factors involved,
including the type of attack (hasty or deliberate), enemy
unit detection level (DL), defending fortification modifier,
attacking unit morale and supply status (especially ammo),
individual ground element experience, fatigue, ammo usage
and range of their equipped devices, and leader initiative
and ground combat rating (mech or infantry) checks (15.5).
Ground elements that have successfully passed their
checks will then fire their equipped devices once they
are within range of an opposing ground element. The
chance to hit, and inflict damage and the number of shots
taken, is dependent on the factors listed above and issues
such as ground element speed, size, and the firing devices’
accuracy, rate of fire, and blast radius against soft targets.
For AFV and combat vehicles, additional factors apply such
as where they are hit.

[...]

The amount of ammunition on hand impacts the
number of shots taken in combat. If this is over 100
percent, the combat unit may gain an extra shot. If less
than 50 percent, the combat unit will likely have fewer
shots than their weapon might allow. Longer range artillery
units will fire less often if their ammunition stock is under
75 percent.

ROF and ACC
Modifier to a device’s base rate of fire (ROF)
and accuracy (ACC). ROF (Rate of Fire) and ACC
(Accuracy) are modifiers. ROF is a negative modifier
that is applied to vehicle mounted devices to reflect
the restrictions of operating the device inside the
vehicle. ACC is a positive modifier that increases
the accuracy of the device to reflect both a more
stable firing platform and superior optics.

further remarks:

23.6.3.
Before 1944, Soviet artillery and rocket ground elements
(i.e. both those in units and specialist Support Units)
will have a notional requirement for only 60% of their
ammunition needs. In turn, this will reduce the rate of fire.
Units reporting (directly or indirectly) to a Front set to
Assault Status (21.11.2) will have a notional requirement
for 90% of their ammunition.

21.2.1.
So while a given weapon system has some notional
capabilities it may be lower in practice when assigned
to a particular tank or vehicle. As an example, the
Soviet 152mm gun is less effective mounted on a KV-2
than on a late war ISU-152.

The main rule in the game, IMO, is that big numbers defeat small numbers, to be honest. 200 000 Soviets versus ~17k Germans is a perfectly fine strategy for example to be pursued.
