The Heavy Infantry Team or 'HiT' for short, are a group of specially trained Marines.Usually called in when the Colonial Marines cannot complete the assigned mission on their own. HiT squads are specially equipped with the best gear credits can buy, and are recruited from the best marines who can prove them self in the basic training and advanced training courses, and in most dire of situations.
Your goal is to assist the marines in their mission, what ever said mission maybe, either to reclaim a station or evacuate. (You don't know Xenomorphs are until' you are told, or see it with your own eyes) The first step as a HiT member would be to find the Commanding Officer, get more information and your missions. Then assist the marines in whatever they need. Your goal is to protect the marines as best as you can, as you all try to get the goal accomplished.
