From Mexico, no, but that's simply because that country entirely lacks any sort of combat capable air force. 80% of it is observation planes (Cessna, Pilatus, etc) with some decent recon aircraft for internal policing; the rest is some lift capability in the capital (ostensibly for VIPs) and transport helicopters. Bazooka Charlie would be a legitimate ground-attack threat in that environment. Their army on the other hand, that's a bit more of a threat at both a decent size and well-equipped even if it lacks heavy armor units.
From CANADA, well, we've had War Plan Red since the 1920s, and the military does come up with weird scenarios for both "just in case" situations as well as outside the box training, and breaking the 'but that can't happen' mindset. And Canada, at least, has a decent tactically-capable air force compared to Mexico.
The Marines practice some weird ideas; a friend of mine in 3MAW mentioned his battalion doing an exercise where their base came under attack by ghosts. They had to figure out what was happening, how it was happening within the rules of the scenario, figure out what those rules were, and then handle the situation.
