Starship Troopers was loosly based on the Novel by Robert Heilein.

It is a film about the military through training and active duty against the "bugs" an alien insectoid race.

The tech in the film is closer to what you may see in Halo then you would in Star Trek. The Star Trek weapons are so advanced as to have stun and kill settings with the kill setting so brutally effective that vaporises and an opponent and it negates the practicality of even heavy armor. Starship Trooper weapons feel more near future, the rifles are obviously powerful but they do not appear to have variable functionability or the ability to vaporize an opponent. The armor is a light power armor.

My vote goes to the Starship Troopers Federation because, unlike in the movie, the Mobile Infantry Cap Troopers from the novel are in powered armors and are better armed than the MI from the movie. I just don't see how a bunch of guys walking around with laser guns and no body armor can stand a chance against power-armored Mobile Infantry Cap Troopers. Now, as for the starships, the Starship Troopers Federation would only need to arm one starship with a single Nova Bomb to destroy the Star Trek Federation's entire fleet.

The 'away team' is not the nited Federation's equivilant of marines. They are more of a lightly-armed research party. And a phaser blast will easily turn an entiere troop of power-armoured marines into dust.

the m.i.'s powered armor allows them to move at a considerable clip and attck from long range, something that federation ground forces lack(check out the ds9 episode " the seige 0f ar-588")
