I have been experimenting with targeting modules. In certain ships certain modules appear to be vulnerable. With Alliance ships I've have had some success targeting the drives then the power plant. With the ship generally exploding before the armour runs out. With the Viper the power plant seems a worthwhile target straight away. However I have also targeted the drives on an Anaconda. Ha ha it seemed to say. I'm guessing people that do this have their own approaches for different types of ship.
