There are terminology issues with the RPG-7 series. I have seen a number of sites state the RPG-7 was actually named RPG-7V right back to it's inception
"The RPS-250 grenade launcher was assigned the designation "RPG-7V" and the grenade used for it was allocated the designation "PG-7V". The operational service and fire-range trials were successfully conducted in 1961 "
http://www.bazalt.ru/rpg-7v-eng.htm
then later..."The PG-7VL round offering increased armor penetration was adopted in 1977.
http://www.globalsecurity.org/milita...pg-7-specs.htm lists the VL round ....
NamePG-7VL Caliber (mm)93 TypeINA Range (m) Effective300 MinimumINA PenetrationArmor (mm) 600
That matches the "RPG-7V" we have in the game and that matches the armour penetration and it matches the date it appears so the RPG-7V we have in the game now may not be ....."too overpowered. In game it have HEAT pen 60"
The "VR" round intoduced in the late 1980s in one we are "missing" but I have seen it's penetration specs listed as " 600-700" in one place and 750 in another. This is not unusual with weapons but it's not too far off what we have for the "V" because Heat penetration is taken as the actual penetration number plus a random number based on warhead size so the "V" can actually penetrate to 650mm if you get lucky
I'm reluctant to alter this mainly because so many nations use this and each of those nations have many units that use it which creates a lot of work for a little benefit and we are up to our ears ATM with the other patch fixes
