I'll pass on the video; after playing BF for a great amount of time I've noticed that 90% of the players don't have a clue. If you fall within the 10% that have a clue, you can pass on any video talking about BF gameplay; if your in the 90% range study really hard then do a nose dive off anything higher than 40ft.
But I know the good ones in my squad. I play medic with the medic perk, I know how to set squad objectives and play them and I can charge MY FUCKING PADDLES BEFORE REZZING.
I think the squad setup is most of how well it will go. With voice comm and staying together, it goes a whole lot better. A good medic is also critical for a squad. IMO of course.
