How hard is it to fly? How much training will it require? How much continuing practice will it take in order for the driver to maintain proficiency? How many guys in a particular unit will be taught to work the thing? What kind of winds will it handle? How will it do in rain and snow and blowing dust? How will the thing take being stored in wet, very dry, very hot, very cold conditions and air laden with salt? Can the radio link be easily jammed? If you had a really sophisticated enemy could he steal in from you in the air and fly it back at you? What are you going to do if there are a lot of trees around? Does it really give you anything more than a properly developed XM-25 will give you? What if the enemy is hiding under a bush and there are lots of bushes around?

How come nobody tells those guys in the video to settle the hell down and quit trying to see who can get the most excited?

The basic idea has promise but there are a lot of practical difficulties that stand in the way of it being useful. The most important question about something like this relates to something Bill said (and Ken says too), will this really be more worthwhile than good infantry skills developed through proper training?

And lastly, maybe there would be a good thing coming out of the enemy getting something like this. Shotguns for everybody and lots of skeet and trap practice to keep the base safe.
