The base game rules seem to say that you can choose one of three actions when activating a viper: launching a viper, moving a viper, or attacking with the Viper. It then goes on to say that you can activate a viper any number of times in a given turn. So, the way I read it is: you choose one of the three actions, and then you may take that action any number of times with that Viper on a turn.
Obviously, if you're launching a viper, that's the only thing you can do with it for that turn, unless a card or ability gives you another action.
However, if you're moving the Viper or attacking with the viper, you get to do that multiple times in the turn, provided it's the same action. So, I can take my viper from a given space, and basically move it around the board to wherever I want. Or, if I'm using the attack action, I can attack any number of raiders in the space with the Viper on a given turn.
Am I interpreting this rule correctly?
