So I was contacted by a PR representative for some company who asked me if I wanted to test an M17. I didn't let on at the time, but I had no idea what exactly an M17 was. I knew what an M16 was.
And I knew what an M18 Hellcat was.
So I figured an M17 was something between the two. Perhaps a massive bazooka or maybe a fixed gun emplacement. It sounded fun either way. I enthusiastically agreed. Imagine my disappointment when it showed up and it was only a laptop computer.
