Taking the new Pummeller and Impact Incendiary Grenades for a run out and find a Meta loadout vs Terminids.
Now my accuracy.... let's not talk about that.... but the combo between the AX/LAS "Guard Dog" Rover, G-13 Incendiary Impact Grenades and the SMG-72 Pummeller.... as the cool kids may say 'SLAPS'.
Create a firestorm between a bug hole that's spawned up and as they come spewing out into a sea of fire, the Pummeller staggers them keeping them in the fire and the Rover takes them out.
A secondary weapon in the GP-31 Grenade Pistol for taking out bug holes at the nest sites and those last ditch moments is a good addition with either of the Grenade Launcher or the EAT-17 Expendable Anti Tank strategems.
The CE-27 Ground Breaker armour gives you the extra 2 grenade capacity and reduces recoil by 30% if you crouch (a one handed SMG this is a big help!)
