I interviewed at a company that was a leader in bullet proof vest, gloves and gun holsters. I would have happily done the work. If I can make a better bullet proof vest and protect someones family member then I will. To me this is not a moral conundrum. There will always be soldiers and they are an important part of our countries defense. If I can help save a life I feel inclined to do so. They also had some pretty cool facilities on site including a testing chamber for the protection items. Would be awesome to see that in action. I do draw the line at actual weapons. I have no interest in guns and even less in missiles. But I would consider working on cock pits for planes or driving consoles for different craft. I just don’t do point end of the spear stuff.
