That's fair.While this is true, I just simply don't see it in most of the movie.
I think the film's equally a satire of big, dumb, Hollywood scifi films, despite being precisely that. It's mocking itself --most of the time with a completely straight face.I don't see the satirical aspects of things like the attacking ships being so close they are colliding in space. Or the troopers having essentially no heavy weapons or any kind of support (arty, air, orbital artillery, etc...).
However, I do think it's a little unfair to criticize the lack of (any sort) of military realism in the film. Most military scifi fails in that regard.
