Attrition and accidents
Attrition is the loss of equipment — not manpower — during the course of a war when fighting on the offensive. While only land units suffer from attrition, air units may suffer accidents, especially when moving in a harsh weather, resulting in loss of equipment.
- Training: 6% attrition.
- Terrain: Up to 50% attrition.
- Weather: Up to 70% attrition and +60% rate of air accidents.
- Resistance: Up to 25% attrition.
- Out of supply: Up to 30% attrition.
Higher reliability reduces equipment loss from attrition.
For land units, the average rate of equipment loss per day as a proportion of total equipment is
So for 100% attrition and 0% reliability, about 10% of equipment will be lost per day. At 80% reliability, 100 days of training (enough to go from Green to Trained, or halfway from Trained to Regular) will cost about 15% of equipment.
While aircraft do not suffer from attrition, they have a chance of accidents when taking off/landing. This is
or equal to 1% attrition for land units. Carrier-based aircraft suffer twice the accident rate. It can quickly turn into a major issue, chewing down through the pool of accessible planes regardless of how well the air combat goes.
Ships do not suffer from attrition, but the reliability corresponds with probability of getting critically hit by enemy attack.
Methods to reduce equipment loss
There are several ways to reduce the effects of equipment loss. One way is to improve reliability by attaching a Maintenance Company to a division or creating new variants of equipment, such as tanks, ships, or planes, with increased reliability. Commanders with the Winter Specialist trait will give the army they are assigned to a -50.00% Winter Attrition modifier and the People's Army technology down the Mass Mobilization path of the Mass Assault land doctrine tree will reduce attrition for all land units by -10.0%.
Custom difficulty settings
Adjusting the strength slider of a major country prior to a game will reduce the amount of attrition that that country's units will receive. However, doing so disables achievements.
