Does anybody know how to make these tanks work in PvP / Glob-ops>

I've been trying and mostly failing but here's what seems to work thus far:

- Flanking, only works on certain maps like Roughneck

-Acting as a turret in a good position (ie, middle of the friendly team's ridge line on Airfield

I'm using Sabrina as my commander

Is there a better playstyle / commander that I'm missing?

EDIT: After realizing that there is already a similar thread, I am now asking more about play-styles / positioning.

Any tips towards using this thing effectively? I often find that I don't do very well in global ops even with most of the upgrades. Any tips?

Thank you good sir, will take not.

Quick question regarding the M1 TTB on this season.

I noticed that sometimes I have trouble regarding getting the best efficiency out of the ready rack, particularly on chapter 2. Since there are so many enemies on chapter 2, I either try to wait out the full reload or fire when I have loaded 3 or 4 rounds. Which way is best? It seems to be that the  3 or 4 round solution works better, but some second opinions are requested. 

For reference, I run Katherine Grey as my commander.
