This one is hard for any noob, rookie or even a good Mud and Blood player. Surviving 100 waves is difficult, but to survive without anyone dying is an extra sprinkle of difficulty. That is really hard, unless of course, you follow a strategy that works well. The rewards are good and worthy of respect, so it is a good ribbon to have. Note that the medal employs the visible wave counter. It will make your profile look good as well.
The requirements, sadly, are bugged, because it does not count Gibs as proper kills. The reward is fully operational though.
