Operation Endgame

I'm about to tackle the last mission (no mods), and I've got a question before I jump in and kill myself. What should my team layout be? I have the Valkyrie, with 10 troops and a Hyperion tank. Currently I have 2 snipers, 1 shield, 1 heavy, 2 riflemen, and 4 assault. I have all the tech (and equipped with MAG weapons and Sentinel/Predator armor). I'm wondering if I should change up some roles.

You don't need a tank there. At least I did it without vehicles.

My layout was next: 4 heavy (2 MAG storms and 2 Singularity cannons for the test purposes; 4 MAGs would be better), 4 assaults, 3 snipers and 1 rifleman. And don't forget about the smoke and fusion grenades.

No tanks here either, 5 heavies(storms) 2 snipers.. the rest was assaults and rifles. Brought lots of explosives as well.

I brought a Hyperion along but mostly because I had been using it for other ground combats and didn't have any decently experienced troops that could have filled the space. I did find the big explosive punch useful in one or two of the rooms.

Thanks, I'm probably going to get a few more heavies. Would a rocketeer be useful?

Was fun for me to deploy 2 snipers, 3 singularuty guns (to have fun with reapers), 7 MAG heavy.
