Normandy is the dream ship for many soldiers to serve on, and many soldiers dream of being in Commander Shepard's squad. The war is brutal, and Commander may need help at any moment.

They need to choose the best operatives who can work very fast and effectively in three-person squads and succeed in toughest circumstances.

"So, what about good old fire?" she asked. "Can I count on your help with this?"
"Of course," he nodded. "Good old fire, and then they'll have your Shockwave right into their ugly faces."
"Here comes the big BOOM!" she smirked.
"Freezing and shattering them would also be nice. I'll help with this."
"Look... Can I ask? You still think you'll be chosen to serve on this ship?" she inquired.
"Why not? This is our human ship. If I am good enough..."
"It is also of turian design, so turians will definitely try to get a place among Shepard's operatives."
"Not only turians, but also asari, salarians, quarians... all sentient species, even geth! The whole Galaxy wants to help Shepard. So, we humans have the same chance as anyone else."
"Well then, all that's left is to prove that you're the best of the best. Like Shepard is.
"We still need to survive first. So, grab your gear and stay focused. Let's blow them all up!"
