Helldivers 2 - Sniper build now is Better - Helldive difficulty

I wanted to try similar build but with Eruptor, but knowing that Eruptor requires to manually chamber a round after every shot, I think using the Dilligence Countersniper is better. One question, how would you handle if there's a swarm of enemy very close to you?

you played a great support role being smart and staying out of CQB. I'll likely give a loadout like this a try
