Nobody went to bat for Polar Patriots so I will. The pistol side arm isn't fancy but reliable. The Pummeler SMG makes the Ballistic Shield stratagem viable.
I don’t see enough people using the Pummeler and Ballistic Shield. I know it’s not meta, but it’s just so much fun to slowly advance on bots while laying down suppressing fire. I feel like it helps the squad push into tricky spots too.
