Thunhus said:War Machine rules have some big holes. Army of 8st level characters are slightly better than 1st level characters. But army of 9th level characters (+200 BR) are much better than 8th level. That leads to high level (9+) small units that are almost unbeatable.

Like I said, with War Machine the GM needs to set the Basic Force Ratings & Battle Ratings with common sense & judgement. Then the actual combat resolution is a doddle. Here's my detailed War Machine Basic Force Rating system for 3e - I took the best bits from the OD&D Rule's Quick Force Rating system as well as the detailed system:
War Machine 3e
Detailed System:
Basic Force Rating
Force Leader's Leadership score (Level+CHA)
+ Average Officer Level (1 Officer/40 troops)
+ (Average Troop Level) x10
+1/Victory in past 10 years
-1/Rout in past 10 years
+ Training Factor: Green - 10 Trained - 15 Regular - 20 Veteran - 25 Elite - 30
(eg Commoners are probably Green, Experts probably Trained, while Warriors are Regular or Veteran, & PC-Class troops are usually Elite)
Weapon:
+ the maximum damage of the most common weapon
+5 if weapon is masterwork
+5 if second weapon of equal quality
Armour: + (AC-10) for most common armour
= Basic Force Rating
Then add factors as normal to get Battle Rating.
Quick Battle Rating - especially for monstrous forces.
Average Troop CR - for most armies this will be 1 or 2 ranks (+15 or +30) higher than the CR of the weakest or most common troops, eg if the typical troops are CR 1/2 (eg orcs) the average army CR for an orc army will usually be 2/3 or 1.
The table is based around the "average force" - eg human regulars - being BR 100. Taking the CR of the weakest troops and adding on the leader's Leadership and the average Officer level also gives reasonable results - eg Orcs CR 1/2 with 5th level officers and a leader with Leadership 10 would have BR 85, TC Fair.
Average CR Battle Rating Troop Class
1/8 10 Untrained
1/6 25 Untrained
1/4 40 Poor
1/3 55 Below Average
1/2 70 Below Average
2/3 85 Fair
1 100 Average
1.5 115 Average
2 130 Good
3 145 Good
4 160 Excellent
5 175 Excellent
6 190 Elite
+1 +15 Elite
