but here is what it says:
Bombing Run (BR)
When this attack is used it destroys a % of all the enemies buildings as well as lowers his/her readiness.
The max readiness loss is 60%. It will not drop below that.
bombers are a attack unit only. They will NOT defend against Bombing Runs.
Jets and SAM's do defend against a Bombing Run.
Below is the percent loss for buildings in the attack.
Residential- 0.01
Commercial-0.01
Industrial-0.02
Farms-0.02
Science-0.02
Construction Zones-0.005
Out of war attack will cost the attacker 25% readiness loss per turn
In war it will cost the attacker 20% readiness loss per turn.
Of course these vary depending on offensive to defensive amounts just like all the other attacks have.
