Attrition is the loss of military forces from causes other than combat. In the EU2 timeframe, far more men were lost from disease, exposure, and desertion than combat.
This page discusses general rules of attrition applying to all military units. For specific information on the computation of various kinds of attrition, see the linked articles:
- Land attrition - supply-based attrition for land forces.
- Naval attrition - supply-based attrition for naval forces and their passengers.
- Movement attrition - for both naval and land forces.
Types of Attrition
There are two kinds of attrition:
- Movement attrition, which applies to most moving units.
- Supply attrition, which applies to any units without sufficient supply.
Application of Attrition
All attrition is quantized: it is computed and applied only at the very end of each month. This applies to all attrition: movement attrition and supply attrition, for both land and naval forces.
