The internal formations of DarthMod use the new protective formations used by many melee units (Something like shield_wall) and also force AI to swap between modes.
Other mods do not have this so if someone plays with internal formations another mod he will see heavy units to prefer a loose formation which is undesirable.
Except from general tweaks there is also a major new attribute that I use to play with internal hard coded CA AI to force for example Hellenic phalanxes to hold their stance and cohesion than phalanx/unphalanx. Maniples to be more maneuverable, Macedonian cavalry to prefer wedge formation. And a combination of things that enhances too much the AI battle thinking.
These formations have a unique character for each faction something first done for Rome:Total War.
That means, each faction will use specific formation roles to fulfill its needs according to faction’s strength and weaknesses. No more randomness and irrelevant formation styles. You will witness an AI never seen before, which uses strategies taken from actual history of each culture. Each set of formation will swap between roles and according to circumstances, AI will use a variation to attack, defend, maneuver, turn, flank, retreat with extreme accuracy.
These formations are 100% combatible with original RTW:1.3/1.5. versions (Or simply play old campaign with version 1.6 = purchased BI). If any mod makes alterations to the factions used by RTW then it will not play.

Also Siege tactics are enhanced and different strategies will be used by Eastern, Barbarian, Greek and Roman cultures.
Bridge AI tactics are also enhanced to provide a crash of human forces from the start of the battle and also less fatality of generals.(updated 15/3/2006)
Human formations are enriched with adaptation of most of the above mentioned formations to the custom based formation of the game.
To use them select all or a proportion of your army, group them and select one of the special formations with efficiency. Special adjustments have been made to preserve the alt-click keep of formation.
