Air defenses in the RL

[Mt5_Roie]

I'm starting to develop some missions for training and for fun. Eventually I'd like to take a crack at making a campaign. But it got me thinking - how are air defenses placed in the real world? Is there like a NATO standard or a Russian standard setup for protecting an airfield or a town.

 

I'd like to develop a base mission that I can use to modify with situations but I'd like the base mission to realistically re-create some air defenses of the enemy.

 

Any thoughts, or websites you guys can recommend?
