How to unlock the Nothing Turret achievement in Earth Defense Force: Insect Armageddon - Definitive Guide
Base turrets are simply the turrets you'll encounter throughout the game. You'll accumulate kills as you progress through the story and levels in Survival Mode also have turrets you can use to acquire this trophy. This is more grind heavy than difficult, just keep at it and be patient. Like the tank, there is a chance you will get this on your first playthrough.
Best place to grind these kills is in Survival mode. The map Cornerstone provides you with a turret right at the beginning of Wave 1. Grind your kills here. If the latter waves are too tough just repeat Wave 1 until you've reached your 500 kills.
These first show up in the second mission, and you'll likely earn well over a hundred between it and the third mission alone. You'll get quite a few kills with this during the course of the Campaign/Survival so there shouldn't be any need to grind extra. If you want to knock it out quickly though, play Map 1 (Cornerstone) of Survival.
