Dumbest. Military. Ever!
There is a good thing/bad thing perspective on putting the first minutes of a movie like this on YouTube for free. Good is that potential viewers can see what the film is going to be like. Bad is that potential viewers can see what the film is going to be like. :-)
So, honestly, these are troops from Area 51, which in this movie, like really all movies, really IS a place that keeps the most scary secrets of the country. Now, you would REALLY expect these personnel to be the elite of the elite, especially if they are transporting the most dangerous thing in the world.
But, they're instead a bunch of doofuses, yacking about mindless stuff, acting like the whole thing is just a joke. And, the zombie thing they are hauling is is a standard shipping container. So, the second a car hits it, it instantly springs right open, unleashing a creature that can destroy all humanity.
The lesson I took from this? This is going to be an IMPOSSIBLY stupid film that should be avoided like there is no tomorrow.
