At a dextro bar in the Silversun strip, Citadel:

Quarian Soldier: So there I was taking cover behind a pillar in the middle of an old military base on Tuchanka. A Prime was pinning me down but luckily my shields started to recover in time for a quick escape to the shuttle. All of a sudden, my shields were damaged and a cloaked hunter unit was right behind me. Having exhausted all my consumables, I was one hit away from being left for dead on the battlefield.
Quarian Engineer: "Oh Keelah!"
QS: "And out of nowhere, the hunter just flew into space as if launched from a cannon."
QE: "Vanguard charge?"
QS: "No"
QE: "Ah, Tuchanka! A krogan’s raw strength with their back slap is amazing."
QS: "Not a krogan either. It was a human biotic. Wielding a shotgun with an omni blade, no less."
QE: "Whoa!"
QS: "Whatever happened to biotics and engineers having to keep their power recharge speed high."
QE: "That’s just recruit-reading!"
Turian Sentinel (overhearing the story): "Spirits! I had a similar experience with a vorcha helping me and my partner take down an atlas. With his claws!"
Turian Engineer (also overhearing the story): "I co-ordinate several cross-species missions and reports of such soldiers are on the rise. Recently, I was approached by a shadow organization training multiple races on their melee abilities. They even offered to retrain me to use sabotage ability to double my omni blade damage. In return, I had to deploy some of their soldiers."
QS: "Drell? Volus? Geth? Is this a joke? The ones I am teamed up with could barely stay alive!"
TE: "I thought the same. But these soldiers are some of the best I’ve seen!"
