Attrition and accidents bak
Land units may suffer attrition and air units may suffer accidents especially when moving in a harsh environment, resulting in loss of equipment.
- Training: 6% attrition.
- Terrain: Up to 80% attrition.
- Weather: Up to 30% 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.
