Just for the heck of it I am trying to get all of the basic badges. First I was doing it just for fun but I am finding that there are other benefits. Most of them force you to try different styles of play or weaponry which leads to a more rounded soldier. For example I spent 10 minutes flying around a transport helo while playing a 64 person dragon valley game. While I was not helping the team that much I was learning how to pilot a helo and deal with things such as landing so I could repair some damage. I am trying to get my explosives badge now which is kinda tough (13 kills using explosives in one round) but I am getting better using C4.
Give it a try you might find it fun and beneficial. A list of the awards and their requirements can be found on the planetbattlefield site.
