Now, perhaps you’re just getting back into Destiny 2 and really want a great rocket launcher people won’t make fun of you for but all of this sounds like way more work than you were counting ...

There's the classic bazooka –its official name the M9A1 Rocket Launcher– the RPG-7 anti-tank grenade launcher, the more modern AT4, the Carl-Gustaf M4, and the RPG variants (RPG-32 and RPG-75M).
