True, if they could get one in the air fast enough to the right place quick enough. DMAFB has A-10s, but how long would it take for notice of a narco tank across the border to get up to the Air Force, authorization to dispatch the Warthog to actively search and destroy an armored vehicle? I would LOVE to have CAP flown over the border by A-10s, that would be awesome, but very very expensive. I also confess to having less than zero knowledge of Air Force operations, so I may be way off.
But I am betteing that such a vehicle could make a short foray into the border, cause hate and discontent, and be gone before an A-10, given day to day normal operations, could arrive. Once again, I could be and hope I am dead wrong, even though I seriously doubt these beasts will make many appearances across the border.
