also you can join other squads too , or other bases, i'm new at this (F4AF) so i'm still learning my self, i like the whole Dynamic campaign of F4AF, it does make you feel your part of a large campaign operation .
unlike Lomac where you just fly a set mission where every thing is the same every time you fly it, you begin to know eactly where and when the enemy is gonna attack or appear, hey but you sure look pretty fly the mission, it's like that movie ground hog day . there i got my Lomac bashin out of the way.
in F4AF as i said i'm new at this sim , i made the mistake of setting campaign on veteran and i'm getting my a_s kicked , but i have another campaign set as rookie so i jump back and forth,
and it's always all different no Ground Hog Day here .
