Lasers? Okay.

 So, YouTube claims that the US Navy is using lasers as weapons in the strait of Hormuz.

Go watch.

I was personally using lasers in the M60A3 in the mid-80s.  We used them for ranging and we thought that the ability to do so was high-tech, whizbang science.   Now, the Navy is shooting down drones with them.

Well, this is the 21st century.
