The last I read, the billions are counted against the hardware we send over rather than sending cash in that amount. No wonder we're hearing about ammunition shortages in our military! I still give money for stuff like uniforms, vitamins, sutures for C-sections, and medic supplies. Will we ever get a really accurate accounting of the money publicly? I'm not sure. I know our ever-trustworthy gubmint has officials who watch where the money goes over there.
The "mini-gun" will probably spawn something more effective. The bullet drop and not leading like he should on the target makes this an interesting, but probably not effective weapon.
