Goliath Tracked Mine — Nazi Suicide Drone

I've always enjoyed articles on WW2, as my father and his brother, who was killed, were both in it. One was in the Pacific theater and the other was in the European theater.
Back to the article, I had never seen an or heard of these mini tanks and I appreciate this article and the knowledge that they existed. Quite the invention back in those days and how the improvements were made up to this date.
Thank you for the fine article and I'm looking forward to learn more about WW2.
