I thought an RPG _was_ an EFP? The round is just a shaped charge with a copper liner that penetrates the armour. So the slatted armour stops both RPGs and EFP-based IEDs.

The usual RPG with a HEAT shaped charge doesn't destroy by forging a penetrator that then potentially travels some distance to the target, it produces an intense, narrow jet that'll cut through a lot of material.

Not really. EFPs (in Iraq) were more or less IEDv2 in that they were simply much more lethal than the original IEDs:
