I have been using pro and been trying to write a fictional story set in the modern day. Long story short ChatGPT is really on the fence of exploring anything related to military equipment and lethal capability. It always assumes civilian control and non-lethality.
Even when I give a prompt about fictional engineers trying to design military equipment and vehicles. Instead of giving a neutral answer with military oriented objectives. It always goes towards non-lethality and coherence with international law.
