Experience, often abbreviated to XP, is gained at the national, commander, and unit level. It is used to modify land divisions, ships, and planes, and is mainly earned through combat.

National experience[edit]

National experience is gained during combat and training, including volunteer forces and lend-leased equipment. Advisors who are Theorists give daily static bonus to experience they are specified to. Some national focuses and ideas can also give national experience. There are three types of national experience: army, naval, and air, each can be used to modify their respective branches. Storing of experience at national level is capped at 500.

Army experience[edit]

Navy experience[edit]

Air experience[edit]

Commander experience[edit]

Main article: Command group

Commanders gain experience as the forces under their command engage in combat. There are no air commanders, however, air combat may generate Aces. Aces boosts the air group they are assigned to, and give the best bonus to small air groups. The listed bonuses for aces are the bonuses given for an air wing of 100 planes. Commanders have skill levels to indicate their gained experience. These skill levels affect four skills - Attack, Defence, Planning and Logistics. Each Skill Level of Army Commanders gives a flat bonus - +5% to Attack or Defence, +5% planning speed and +2% max planning, or -2% supply consumption respectively. Each Skill Level of Naval Commanders increases Fleet Coordination and Naval Hit Chance. The current advance to the next skill level can be seen by hovering over the skill level number. Commanders do not only gain experience but also traits during combat, which give more situational but still helpful boni.

Unit experience[edit]

Individual land and naval units also gain experience. This gives a modifier to combat:

Experience level Minimum experience Modifier

Trained.pngTrained 10% 0%
Regular.pngRegular 30% +25%
Seasoned.pngSeasoned 75% +50%
Veterans.pngVeterans 90% +75%

Newly deployed units normally begin with Trained experience, but can be deployed early with Green experience. Exercising units in the field allows them to advance up to Regular experience level, at the cost of time and equipment. Higher levels can only be gained through combat, and naval units can only reach higher levels through combat.

Replacing casualties reduces the experience of a unit. This loss can be reduced with Field Hospitals.

Changes to the template reduces the experience of a unit.
