Read this on IMDb about the movie Blackhawk Down. Funny, being a superpower country and having one of the largest movie making industries in the world, we never worry about such things:
The production imported 100 Rangers, a dozen Humvees and 8 Black Hawks into Morocco for filming. This was considerably more firepower than anything else in the country and the Moroccan king was understandably uneasy about allowing such a large foreign military presence into his country. Ridley Scott joked that they could have taken over the country if they'd wanted to.
