Using SOPMOD as my carry for corpse dragging 0-2. I must admit that it's really satisfying to look down and watch the grenade go off and now half the enemies are down for the count.
M16A1's stun grenade is a lot more boring tbh.
I'm grinding both of them because IMO the AR team as the protaganist team deserve to be lvl 100 even if I mostly use them for logistics...
