'''Combat tactics'''<ref>See in {{path|common/combat_tactics.txt}}.</ref> are determined for both sides at the beginning of a battle.

'''Combat tactics'''<ref>See in {{path|common/combat_tactics.txt}}.</ref> provide damage, defense, movement speed, and combat width modifiers in [[land battle]]s.
  
Each side has a weighted list of available tactics to choose from based on the current battle phase, commander skill (and reconnaissance advantage), researched techs and the fulfillment of other special prerequisites (as shown below). If successfully pulled through tactics may provide damage, defense, movement speed, and combat width modifiers. If an enemy's tactic is countered, they do not receive the benefits from their tactic choice.
+
Tactics get re-selected every {{hover|NMilitary.TACTIC_SWAP_FREQUENCEY|12}} hours from a weighted list of all available tactics. The side having '''Initiative''' gets an increased chance to '''counter''' their enemy's tactic. If a tactic gets countered, all its effects are disabled.
  
Battle reports in progress show the combat tactics being used by each side for the current day, with a big red 'X' on a tactic if it is being countered. In the middle there is a button that displays a list of all available tactics (with unavailable tactics padlocked).
+
To determine initiative, the leading generals' skill levels are compared. The side with the highest recon value in one of their divisions (including reserves) gets a bonus of {{hover|NMilitary.RECON_SKILL_IMPACT|5}} skill levels for this comparison. The side with the higher effective skill level gets Initiative.
  
'''Note''': Reconnaissance advantage is determined by comparing the sum of recon values in all divisions in combat of each side. It translates to a flat bonus equal to <abbr title="RECON_SKILL_IMPACT">'''5'''</abbr> leader skill points. The side with higher total leader skill points has combat "initiative" to pick a counter. The side with initiative will pick their tactic after the other side, and if a tactic is available to counter the other side's tactic its weight will be multiplied by 1 + <abbr title="INITIATIVE_PICK_COUNTER_ADVANTAGE_FACTOR">0.35</abbr> * difference in skill points. Reconnaissance advantage doesn't help dodge counters, that is, if the other side's tactic can't be countered and a certain available tactic is countered by the other side, this certain tactic has the same chance of being picked.
+
The side losing this comparison has to pick their tactic first. The side with initiative will pick their tactic after and if the counter-tactic is available its weight gets a bonus of {{hover|INITIATIVE_PICK_COUNTER_ADVANTAGE_FACTOR|35%}} for every point of advantage in the skill comparison. Initiative does not explicitly decrease the probability of picking a tactic that is countered by the enemy's tactic.

Latest revision as of 14:20, 7 July 2020

A battle screen showing the selected tactics next to the commanding generals, separated by a chess piece icon (which when clicked shows all tactics). The attacker has chosen Unexpected Thrust, the defender Elastic Defense. The defender has Initiative, shown by the golden chevrons beneath its general.

Combat tactics[1] provide damage, defense, movement speed, and combat width modifiers in land battles.

Tactics get re-selected every 12 hours from a weighted list of all available tactics. The side having Initiative gets an increased chance to counter their enemy's tactic. If a tactic gets countered, all its effects are disabled.

To determine initiative, the leading generals' skill levels are compared. The side with the highest recon value in one of their divisions (including reserves) gets a bonus of 5 skill levels for this comparison. The side with the higher effective skill level gets Initiative.

The side losing this comparison has to pick their tactic first. The side with initiative will pick their tactic after and if the counter-tactic is available its weight gets a bonus of 35% for every point of advantage in the skill comparison. Initiative does not explicitly decrease the probability of picking a tactic that is countered by the enemy's tactic.
