All right, I'm looking for the title/actors of a sci-fi movie. Moderately certain that is was made SOMEtime in the nineties, likely around the release of Wing Commander.

Movie goes as such:

A group of 'cadets' goes on a training mission with an instructor. While on this mission they are attacked by the 'enemy'. The instructor is killed, and the cadets are forced to fend for themselves against 3-4 bigger ships. Through ingenious means (cant remember them) they slowly take down all the ships, their ship taking more and more damage as time goes on.

Points I DO remember :

2 guys vying for leadership, and a minor fistfight
Woman doctor, rememebring blonde ponytail
The cadet ship is always referred to as a 'corvette' class.
The captain of the force they are fighting is vaguely russian, bald and rather large.

Any help is greatly appreciated.

It could be "Starship Troopers"

Starship Troopers (1997)

Not Starship Troopers, Although I do own it, and it Rocks :)

I'm looking for the same movie... I remember that they hide in a comets tail for a long time to prevent themselves from peing picked up by the enemy... thats all I go though :(

It appears to be a failed series pilot from 1996 called Star Command (not to be confused with the superior Jason of Star Command, aka In the Fold.

Purukivel I could kiss you but that would be disturbing for both of us =P Thanks mate, that was what I was looking for.
