Nice! Gotta save some money, eh?
That’s pretty much how we did our helicopter coordination training back in '79 – one guy in a trailer with an ANPRC-77 radio being a “helicopter”, a bunch of other guys to push him while going “whocka-whocka-whocka-whocka-whocka-whocka”, and us down the other end of the parade ground with another radio and smoke calling him in to the “LZ” 
As weird it may sound the USAAF used something like that in ww2 for turret trainig, only that was a truck the towing apparatus.
I think thats the future U.S. military if Obama gets in office.
Damn… I cant find a photo in the web but I have a book in wich there is several, the guy was in a turret with a shotgun and was towed by a truck shooting down skeet in the move. That supposedly helped aiming Bf-109 in the B-17 and B-24 turrets, I dont now if that really helped but it was amusing to see for sure.
