Squad Tasks

A question about the squad feature you've decided to implement - how deep does it go?

For example, would you group four snipers in a squad and call them a sniper squad (or alternatively, have a spotter for each sniper)?

Or, have a heli pilots (sorry, accustomed to BC2) and three or four paratroopers to sneak behind lines?

Sorry if I'm reading too far into this, I thought it would be cool to elaborate on it.

Yeah, you are too far into it. It's simply just a group of people within one brigade here.
