Hasn't a 'mini-me' version been fitted to a USAF C-130, i think it was pallet mounted with a retractable turret mounted in its belly.
And isn't there a heat type laser being trialled for crowd control that bolts onto a Hmmv. (They did a demo on some journos which I found strangely amusing
)
Wonder if a nice big mirror would be a way of defeating these bad boys!!
