I've seen a large number of threads devoted to "is this balanced" or "is this spell enough" and so forth. I haven't seen a lot of threads that deal with the capabilities of the party as a unit, rather than a set of individuals with cool capabilities. So I'm starting one, and hoping it doesn't die a miserable death 
What are some useful team tactics people have used? Good formations, for various situations? Do any groups even use organized formations, or just run around the terrain at random?
I've started working out tactics for my own group, mostly in self-defense (our party isn't suitable to fight much of anything with an equivalent EL), but I'm interested in seeing what else people have found that works well.
