UNSC Marines Take this Battle.

The reason being is that they have fought more TOUGHER Foes.

They have the X-Factor of Combat Experience on their side, and more better training actually like Swg66 said. Not to mention their body armor will be much more effective. So due to training, combat experience, and better Armor. The UNSC Marines take this Battle.
