What’s a weapon or tactical that’s under rated?

Basically title, I’ve done pretty much everything in this game and it’s getting a bit boring? I’m looking for new ways to play now,
I’ve really done most things, snipers, LMGs, Carbines, rifles, pistols, LAVs, BTR, BRDMs attack helis even just machine gun helis we used tracers to light the enemy helis on fire (this is one of my favorites), we have used gun cars and Humvees to chase down people on roads.

So I want to know what you guys have done that’s super fun for you and your group (that’s in vanilla, mods don’t work for Xbox, too much lag and freezing)
