Nobody likes spawn killers, so the CV.33 meatball launcher goes out and punishes them.
Update 4/15/2023: So the backstory of this is that my team obviously was losing and during the last part of the round my CV.33 was the last tank available. Didn't realize when I respawn the enemy team ended up pushing towards our spawn. Me being a gremlin I decided, screw it let me have my last stand with this thing.
Also yeah I was only using the Anglerfish Crew as the voices because at the time there weren't any other packs available. So I'm not sure if it works now and I no longer play War Thunder. You can probably find the tank skin available though.
