there are so many possibilities now for each class that you can have two of the same class in your squad they're playing completely different roles. for example, the recon class can be set up to simply snipe. aquire your target, range him in, set your scope, fire. anf then you can take an anti vehicle aprroach. you can use your range finder to laser designate vehicles to help at guys anf then use c4 on tanks anf such. its almost mind blowing.
