It's not a secret if the Navy publishes a video if it. I bet you we would be amazed what 'secrets' our armed forces really have and are working on. I bet you my $2 that I have in my wallet that we had that technology ten years ago, however, just as prototype. What you see here is the final product - ready to f*ck shit up.
A buddy of mine at work just showed me this 10 minutes before I saw this post. I remember seeing a vid on technology we have to make tanks instantly camouflage to the surroundings. Just as long as the govt uses it for foreign enemies and thery don't just start zapping citizens with that laser !!
