Hypothetical ME2 Finale Scenario

I have a what-if scenario that I’m curious to know how ya’ll would handle. For the sake of things, let’s say that the Normandy makes it through the Omega-4 Relay transit fully intact and reaches the Collector base with all 12 squad mates surviving the approach.

A few other factors may need to be fudged to make the next part of this situation work (such as the loyalties and squishiness of certain people), however let’s assume that the Collectors are somehow aware of the Normandy’s crash-landing site this time, so you can’t take the whole team on the assault because you now need people to defend the ship from a third route into the Collector base while the rest are away (think of this as a second identical hold-the-line stage).

You will need to keep 6 squad mates in reserve to guard the Normandy; who do you pick and how many of your tanks will stay behind to cover Joker’s heroic ass (who insists on leading this group since the ship is his baby). Keep in mind you will also still need to split the remaining 6 into two teams with a leader and tech specialist, then account for the long biotic walk and extra Normandy crew rescue as-well as the original hold-the-line moment like normal. Who goes where and gets what roles to maximise the chances of success?
