War Algorithm (WOW)

Location

 * Defending Nation: +10
 * On Border: +8
 * City near border +6
 * No former presence, core of army away from battle: +0

Power
Land is always applicable, Navy is only applicable when an attack on the coast is made. Air attacks must be plausible, if you have no air bases in the region you can't use it.
 * Large aerial assault capability +3.5
 * Large naval assault capability + 3.5
 * Large land assault capability +3.5
 * Medium aerial assault capability +3 (if enemy has no aerial power) +2 (if the enemy has aerial power)
 * Medium naval assault capability +3 (if the enemy has no naval power) +2 (if the enemy has their navy stationed in or around the location)
 * Medium land capability +3 (if three or more times larger than enemy) +2 (if less than three times larger than enemy)
 * Small aerial/naval/land capability: +1
 * Land, aerial, and naval is compounded. If you have large naval, medium air and medium land, your score is 9 or 7. You cannot have medium aerial and large aerial at the same time.
 * Power is averaged in a coalition war.
 * Power is a multiplier for development.

Tier 2

 * Germany
 * Canada
 * India
 * South Korea
 * Japan
 * Nordic Federation
 * Israel

Tierless
Any nation not listed above has no tier.

Points: Power Caps:
 * Tier 1 nations get plus 20
 * Tier2: +15
 * Tier 3: +10
 * Tier 4: +5
 * 1 tier above enemy: +2
 * 2 Tiers above enemy: +4
 * 3 Tiers above enemy: +6
 * 4 Tiers above enemy: +8
 * Tier 1 invading a tierless nation: +10
 * These are subject to change over time, though there are restrictions on movement. To push a nation out of a tier (IE you want to enter tier 1 or 2 but they are full) you need to have a larger economy and be all around better than them.

Each Tier has caps on its power:
 * Tier 1: No Cap
 * Tier 2: 8.5
 * Tier 3: 6
 * Tier 4: 4
 * Tierless: 3

 * Urban warfare: Attacker -2, Defender +2
 * Storming on to a coastline from the sea or on to an island, the attacker - 4 and defender + gains 5.
 * Storming in to a desert, high mountains, or jungle the, attacker -3 and + defender gains 4.
 * Armed expatiation in large extremism climates like Greenland, Niger, Nepal and Amazonia will also be very slow due to logistic and climate problems for any would-be invader. In this case the defender gets an advantage of +5 and the attacker gets a disadvantage of -6

Allies

 * Leader Nations: +10 each participating


 * Military aid: +5 each participating


 * Supplies: +4 each participating


 * Cultural Support: +2 each participating


 * Vassal: -2 each participating
 * Vassal is an L: -5
