As I see it the RPG-7V is a questionable weapon to arm anybody in the iraqi OOB.
The denomination itself is debatable, given that the closest match in the real world (600mm of RHA penetration, single warhead) would be the PG-7L as it was discussed here in the past.
And regardless of naming conventions I have found no mention of PG-7L use in Iraq. On the other hand it seems some PG-7VR may have been used.
So I am in full agreement that one or two odd insurgent units should be armed with something better than basic
RPG-7 (or occasional RPG-18/16), but no more than that and weapon 156 RPG-7VR is the best candidate for the role.
