When the main characters are caught between the monster and the Army's attack, we briefly see what appears to be a truck mounted with an MLRS pod launching missiles at the monster. There is no 'rocket truck' like this in the U.S. Army. The closest equivalent, the M142 HIMARS, does not resemble the one in the film. Moreover, each rocket from an MLRS pod would have been much more powerful than is shown, both in the impact and the blast as the rocket is launched.
