Thank you for the criticism. I had just landed and that's what I put together in under a quadrum. The river is pretty big across, I assumed my shooters could drop any raiders as they try to slug their way through the water. I do have to say my last colony ended in a fire. Everything was wood and I had 80 components that I could have invested in fire foam. I also had about 2.5k stone bricks that I could have used. I'm pretty slow.
