Squadron

A minimal squadron  

This is the simplest form of squadron possible. The Escort triangle extends the already monstrous influence of the B2 Bomber, and also gives it support in case (however unlikely) it gets into a tight spot.

Another simple example  

This is an even more powerful squadron, capable of destroying all but the strongest of opponents. Except when they too have their own squadron.

A Dual-Bomber squadron  

This is unbelievably rare, and a terror to behold. Two bombers in formation. This only occurs in games in which both players are working to build their own formations, and is otherwise all but impossible to form.
However... perhaps only once, this rare type of squadron has been created;

The legendary "fleet"  

The special thing about this squadron is not its arrangement, but its sheer size. It radiates power almost visibly across the board, stunning all who behold it. Any formation of such size cannot be defeated under any circumstances without the use of advanced 9P tactics, or of course Nuclear Tesuji. It has earned itself the infamous name of "B2 Bomber Fleet"
