Tactics and Smaller Elements?

[GhostOneBravo]

Hey guys. I'm completely new to Planetside. I just played for awhile and for the most part it just seems like a huge bunch of chaos......i know its partly because I'm a noob and dont know the ins and outs.

But I have a few questions:

Do some real tactics such as basic flanks and such actually hold any advantage?

Is it possible for smaller elements of infantry to really make a difference? Behind enemy lines or disrupting the enemy on any scale actually worth noting?

thanks
