Very easy achievement to get at the moment.
Go to a planetary base, land your ship outside the base and deploy your SRV. Next, drive into the base and search for the power generator (it will show up in your contacts when you are close to one), get a target lock on it and fire your turret. As soon as the generator is destroyed, log out to the main menu and log back in. The generator will be back to 100% so start shooting again, until it's destroyed and log out again. Repeat until you have the achievement.
