Lasers?
Just add some giant robots and you got a deal! I'll condone any war with giant robots and laser fights. Because, that's KEWL!
More seriously, it's funny to see that after a mere ~40 years of development, high power optical devices found their way in real vehicle-mounted. The various "death ray" projects finally came to fruition?
I'm sure if it wasn't for science fiction, the research in this field would have never last for so many years.
