This is how I wage war at war level 3....
First I use a total of
800 fighter planes with
16000 air to air missiles and
1200 air attack drones with
only a few attack drone missiles.
At '200 Quality' which should be efficient enough to take out all of it's air defences (including helicopters)
Then Second, bomb some of the capital/cities/factories or forts using....
650 Presison bombers with at least
20000 bombs at 200 Quality
Which should take out 3 types of ground defences there which are....
Defensive Missile batteries
Defensive anti aircraft missile batteries
and Missile interceptor batteries
Then Finally take out the remaining defensive forces there which are....
Defensive amoured vehicles
Defensive jeeps
Light artillery
and light tanks
Using....
500 anti tank missile batteries with 80000 anti tank missiles to destroy the final defences.
Then 1000 Heavy Tanks with 3500000 tank ammo to finally destroy the capital/cities/factories or forts.
All at 100 Quality.
Then repeat this process until the the country's war index reaches 0, so if you can't defeat a C3 at war level 3, then you're doing something wrong as I use that strategy all the time to defeat my enemies.
I know this may sound expensive, which will be in excess of about 2T to set up all this up, and well worth it for those who like to raid countries often, but by the time you've stripped a country of money and weapons, you've should of made at least 4.5T in cash.
