Battlefield d20: rules for large combats

My Morale rules based a little off GW

Morale

Routed when a Unit has lost over 50% of its force it must succeed at a Morale Check ( DC of Opposing Units AB+1) or be routed. A Routed unit runs at double movement in the straightest, and safest possible direction from the field

When a force reaches the "edge" of a field it is entitled a Rallying check (DC of Opposing Units AB+2) See rallying below

A Routed unit receives a -2 to their AC, the Unit may be flank attacked, and it receives a -2 to its Attack, and Damage Rolls. In Addition a routed unit receives a -1 circumstance bonus to their Will saves.

Chasing ( Unit AoO) When a unit "Breaks" and begins to run the Routing force can opt to give chase. A Unit who opts to chase a Routed unit moves only at its normal movement unless charging

A Unit who opts to chase a routed unit receives a -2 to their AC due to their chaotic surge of victory, but receive a +2 to both their Attack, and Damage rolls

Charging A Unit that charges gains double movement for 1d4 rounds. Charging units receive a -2 to their AC due to their recklace disregard for unit cohesion, but Recieve a +2 circumstance bonus to their Attack rolls [while charging]


Rallying

Units who fall below 50% of their max force, and make their Moral check are considered to be "Making their Last Stand" instead of breaking and running the Unit is effectively Rallied.

A Rallied unit redoubles its feriocity. Fighting twice as hard as they were moments before

A Rallied unit recieves a +2 circumstance bonus to their attacks, and damage. In addition a Rallied unit gains a +2 to their AC, and a + 1 bonus to their will saves.


CR modifiers for Units in stages of Morale

Chasing +1 Routed -2 Charging +2 Rallied +3


New [suggested] Additions to the Force Stat Block

Instead of listing every unit as being 100 Men etc

Use the Max Force rule

A Unit of 20 Dwarven Stormtroopers is considered at 100% Density at 20 50% At ten and 25% at five

Also the Addition of a CR to the Units Stats would be useful for determining the toughness of a Units strength

Example of a CR use

Those same Dwarven Stormtroopers as an elite strike force
Receive a CR 2 meaning that 2 CR 1 Units should be able to Rout it in combat.

A Major NPC might get a CR also

For instance the War Wizard Tharmos ( And Guard) may be a CR of 3 meaning that 1 CR 2 Unit such as the Said dwarves , and 1 CR 1 Unit such as a Unit of Dwarven Regulars should be able to route the Wizard and his Guardsmen

CU or Comman Units are usually a Generals private Unit or the Honor Guard of the Emperor.

Usually a CR 3 or Higher CU's are the elite of the elite troops meant to keep the tacticians or the major NPC's alive. An example of a CU might be the Dwarven Invincibles a unit of highly elite dwarven warrior/ berserkers who each have at least one magic item (if not more) These Items could be magically imbued Battle Axes of Throwing/ Returning or a number of other odities.

Effective Force Level (EFL) The effective point level of an Army

For small battles a DM may want an EFL of 1,000 Points, or even only 500 points. For larger battles a 3,000 Point EFL or more might come into the offing.

Creating a EFL force ( 580 Point army) A Dwarven Army

4 CR 1 Units Axemen (300)/ Crossbowmen (100)
2 CR 2 Units 1 Stormtrooper Unit (20) / 1 Berserk Unit (10)(Rage)
1 CR 4 Unit 1 Dwarven Invincibles Unit (8) ( T/R Battle Axes) Tactician (1)


Suggested EFL for Units by CR ( Not detailing units of 1/2 or less fractions of a CR such as a Medical Unit ( Clerics) CR 1/4)

CR 1 - 50 Points per Unit with a Challange Rating of 1
CR 2-3 100 -150 Points per Unit of CR 2-3
CR 4-5 175-200 Points for a Unit of CR 4-5
CR 6 300 Points for a Unit of CR 6

Higher CR's than 6 should not occur in a battle unless they are monsters such as Dragons ( CR Adult 6, Old 8, Very Old 10, Ancient 11, Wyrm 13, Great Wyrm 14), or the Tarasque (CR 16)

Some other creatures in a formed unit should receive slightly elivated CR's

Creatures such as Celestials, or Demons, and Devils should receive a CR of +2 of that of a normal unit of their quality

Elemental Bloodlines such as Genasi should receive a CR of +1 of that of a normal unit of their quality

Subraces such as Drow, or Duergar shoud receive a CR + 2 of that of a normal unit of their quality.

Also some Creatures should receive a lesser CR than the normal unit of their quality such as a Halfling Footmen's Division, or a Kobold Berserk Unit.

Units whose average size consists of Small receive a CR -1/2 of that of a normal unit of their quality.

Units whose average size consists of Tiny receive a CR -3/4 of that of a normal unit of their quality

Powerful NPC's such as the General, or the Wizard may have their own individual CR a Wizard of low levels most likely will not occur as an individual on the battlefield but will work in a Unit as a medic or Relief valve.

Mid to high level NPC's [To do]
