If you read the book Alien Woman they are kind of pissed that Dietrich killed Frost in the cross fire.
The fact that fratricide has happened throughout human conflict notwithstanding, they took it that Cameron was deliberately trying to show the female marines as incompetent when compared to their male counterparts. Dietrich killed Frost and indirectly Weirzbowski and Crowe, Vasquez killed Drake indirectly, and Ferro crashed the dropship.
But they also thought Lucas was trying to show that the x wings were sperm trying to fertilize an egg (the death star) so take that for what you will.
