i'll get the president on the horn and tell him that he and his defense advisors as well as some of the brightest designers and engineers in the world need to check out the AH BBs.
Next...You dont have the human element. Looking at a monitor and being on scene aren't the same thing. Remove the human element, and its no longer warfare. It's international battlebots, not warfare.
Im not saying that the more guys and gals in harms way the better, by any stretch of the means as i will be training to become one in the not too distant future. And the U.S. military will not anytime soon be transitioning to a fully automated force to do anything, not even clean toilets. Are there some things unmanned vehicles are good for? sure, flying low and slow providing real-time intel on the battlefield. The marines even have a stow-in-pack R/C airplane i saw used in a television program once that was very similar to your tyipcal r/c trainer.
Anyways, the u.s. will not use forces composed of entire r/c machinery anytime soon.
