The system uses the stat block for an individual Speed and Initiative for the unit remain unchanged from the individual stat block (eg an Ogre has Spd 40 and Init -1 so does an Ogre Unit). As usual Units should all be the same (mixed units are possible but require more math to determine averages)2 The basic unit factor is 100. So take the size of your unit and divide by 100(eg 20 Ogres => Base = 0.2) 3 Unit HP = Ave.HP x Size so 29 x 20 = 5804. Unit Rating = base factor x HD x Rank* Rank Green 1, Regular 2, Hardened 3, Veteran 4, Elite 5so 20 Ogre Regulars = 0.2 x 4 x 2 = 1.6 => rounded to +1Unit Rating is added to base creature BAb, AC and Saves5 Reach Factor = Reach/10 (rounded down) so medium sized creatures have reach 0 whereas Ogres (reach 10) get a Factor of +1 used in rolling attacks6. Unit Damage is Average Damage of creature x Unit size (Ogre = 12.5 x 20 =>250)SoOgre Regulars Size 20 HP 580 Spd 30 (40) Init -1 UR 1 Bab Melee 9   Reach 1 AC 17 Sv. Fort 7 Rfx 1 Will 2 Damage (Great Club) 2507 Rolling AttacksThe Attack Roll is set by rolling  (D20 + Unit Bab + Reach factor + Leadership) - Opposed AC eg Roll 15 + 9 + 1 +0 =>25 - 17(opposed AC) = 8* Leadership = level of Unit Leader8 Determining DamagePenetration% = Attack roll x 5 = > 8x 5 = 40%Damage from Attack = Unit Damage x Pen% eg 250 x 40% = 100 (ie the Ogres case 100 pts of damage)* casualties =  Damage/Ave.HP of the creature9. Morale is a Will check with DC equal to opponents Attack role + leadership + mods eg the above Attack role was 8 so Morale is Will vs DC 8* mods could be things like differences in UR (eg a UR 3 unit vs a UR 1 unit gets a bonus +2), terrain, special manouveres and battle progress10 Special Abilities and Spells work as usual11 Formations A skirmish/mob unit has UR 0 and is in Loose formation which means they are not sitting ducks vs Area Effect spellsHaven't worked out how other Formations affect rules - things like Face and Flank will need to be determined. 12PC interactionPCs and Units can interact in two ways either the PC is considered leader of the Unit and uses their own level as the Leadership factorAnother hacknslash option is for the Unit to esentially become stat mods for the PC eg a Barbarian 5 (Bab 5) leading the above Ogre unit would roll their Attack as D20 + BAb + Unit Bab (20 + 5 + 9 = 34). This puts the PCs  at the center of the action but might seem silly to someThird the Unit Ratings can be used as staright opposed roles to determine progress when the battle is just a backdrop to PC actions (ie Ogre Unit UR 1 vs Orc Elite Unit UR 3 => D20 +1 vs D20 +3) Another example  20 Hardered Medusa Size 20 HP 660  Spd 30 Init 2 UR 3 (3.6) Bab 11 Reach 0 AC 18 Sv. Fort 6 Rfx 10 Will 9 Damage (ShortBow) 70 Snakes 50 (+poison 70)So Battle Ogres vs MedusaRoll Init Medusa +3 => 15 Ogres -1 => 12Medusa Gaze Attack Dc 15 vs Ogres Save d20 + 7 => 25* actually I'm not sure about targeting of the gaze attack or just leaving it general...Ogres charge roll Attack D20 + Unit BAb + Reach + Leadership + Charge mod11 + 9 +0 +1 +2 => 23 - 18 (Medusa AC) = 5Penetration = 25% (Attack 5 x 5%)Damage = 250 x 25% = 62 pts damage (or 3 Medusa down)Morale DC 5 Medusa get a +2 UR bonus and roll Will save (6 +9+ 2*) vs dc 5 Medusa hold and go to next attackMedusa unit Size 17 HP 598 Damage Shortbow 59 Snakes 42 (Poison 59)Roll attack Snakes roll 8+11 = 19 - 17 = 2Penetration => 10% Damage 50x 10% = 4 + Poison Damage 59 X10% = 5Total damage 9Ogres Morale check DC 3 (2 + 1(poison)) roll 12+2-2* Ogres Hold*2 UR difference 1-3 = -2Ogre Unit Size 20 HP 571 Damage 250</blockquote>
