The Glasgow
The tension in the air could be cut with a knife, the crews readied themselves for battle. They had done this hundreds of times before hand, but never before in another universe he didn't know what the other crewmen would think, and he hoped that he was on the right side of this battle, if he wasn't then god help him, but he didn't have much of a choice if he wanted to get home these imperials would probably hold the best answers.
"Plot main gun firing solution, and fire at will!" He shouted to his bridge gunnery crew. Within a moment there was a shaking of the ship, as the slug of the mass accelerator fired, speeding through space. The slug would hit it's target, and collapse upon itself dispersing energy equal to that of a tactical nuclear warhead, without all the radiation, across one of the ships. He sent a ping to his boarding crews to leave the ship, and sent another order for his navigation crews to do a full burn away from the cluster of ships. The Glasgow had good range, and the further away they could get the better.

The shuttles passed through the odd energy shields that served to keep the vacuum of space out of their hangar bay. The shuttle side doors opened, and the crews opened up with the door mounted mass accelerator cannons, their rounds were no bigger than a grain of sand but accelerated so fast they might as well be getting hit with high powered rounds. When the shuttles finally hit the deck, the gathered group of soldiers dropped out of the shuttle, the biotics going first, throwing up barriers. The blaster bolts hit them, but dispersed harmlessly with the gathered group of biotics holding the barrier together, so everyone could get into position.
The squads now gathered, the biotics in reserve rushed forward creating a singularity at their targets soon the assembled clones were floating helplessly off the ground. The order for the barrier to drop was given, and the marines focused fire on the floating clones. Satisfied with their results, the orders were dispersed among the gathered HUD's of the marines in the hangar. "Get to the engine room, and find what allows them to move through space, steal data, pacify any witnesses, none were to leave this sector of space to report back to their leaders." With their orders given they pushed out to help the other assembled crews of their ragtag fleet.
A small group of infiltrators cloaked, headed for the engine room. While the others used their biotics, and firepower to support Jason's troopers, and The Aegis' elites on their own missions. Not wanting the other leaders to say they didn't throw in their weight, as well as wanting to preserve as much of the groups soldier pool as possible as there would be not reinforcements for any of them unless they started to recruit locals, and Sarah very much doubted that anyone would want to join up with strangers from another universe. But those thoughts could come later, for now she had a battle to win.
