5.9 / 10 is way to high a rating
This really is a very bad film.
Starting from the mis-naming of the title, it has very little to do with the battle of Anzio.
As US Rangers the participants give a good impersonation of actors pretending to be soldiers, and not pretending very well. They make just about every military mistake it is possible to make, and then add in a few others for good measure. Almost every character is a stereotype, almost everything they say is a cliché.
In the "haystack ambush", a lot of these highly trained troops think that the best way to attack a machine gun nest is by frontal assault, running up-hill towards the guns. They don't just do it once. After seeing a lot of their comrades getting mown down, others think that it looks like a good idea and do the same thing. But I suppose it gets them out of the film early on
There's probably a good film that could be made about the Anzio landings and the subsequent push for Rome, but this certainly wasn't it
