The trailer doesn’t show too much about the trooper that we do not already know. Bioware has yet to reveal the Advanced Classes for the Trooper as of yet, but the trailer shows off how much ass they can kick with their blaster rifles, grenade launchers, shields, and BFGs (Big Frackin Guns). So far we know that the Trooper will have the option of taking the role of a ranged tank, but I am assuming that the alternate Advanced Class will be a DPS class but it could really be anything. Even a field medic healing class would make sense.
