Some of the worst combat training ever
First, I love this film. It has a special place in my heart. It was one of the first movies I secretly watched as a kid. I remember being mesmerized by the film and terrified by the brain bug, sucking the brains out of people. Basically an amazing movie experience!! But as I've aged and matured, I have become more aware of the films flaws (although I still absolutely love watching Starship Troopers!).
Now that my reverence is out of the way, I can get to the meat of my post. The combat training is horrible! Troops run out from behind cover in groups, ignoring any and all logic. It's a bunch of soldiers going Rambo on the bugs. As a result they get massacred by the bugs. The troops have no formation or combat tactics. They stand out in the open, in a straight freaking line, waiting to be run down. Then the inevitable idiot runs out screaming "Get Some," like the swarm of bugs with somehow be terrified of this act.
For a highly intelligent military society, the soldiers are terribly trained. This is what bugs me about this film. The society is capable of interplanetary travel and space exploration, but they have no understanding of basic combat tactics. It's absurd.
