The siege against humanity

You decide that your feeling powerful tonight and want to show it, your going as a warrior. You get geared up and ready to fight, you walk through the thick of the forest, when you get to the lagoon you are asked whether you want to fight as a front-line or as a specialist, front-lines will be put into the heat of the battle and in very dangerous positions, while the specialists will be following from a distance, killing from afar.
