[kikka]

Looking around on the net, I found the following dates:
RPG-7V >1961 single HEAT 330mm 500m
RPG-7VL >1977 single HEAT 500mm 500m
RPG-7VR >1989 tandem HEAT 650mm 200m
TBG-7V >1989 thermobaric 200m
OG-7V >1999 HE-frag 350m
RPG-16D >1970 single HEAT 380mm between 600m and 800m
RPG-18 >1973 single HEAT 380mm 200m
RPG-22 >1985?single HEAT 400mm 250m
RPG-26 >1986?single HEAT 500mm 250m not sure if fielded
RPG-27 >1989 tandem HEAT 750mm 200m fielded maybe 1990
RsHG-1 >1989 thermobaric 200m fielded maybe 1990
RPG-29 >1989 tandem HEAT 750mm 500m optic/800m laser
Might be interesting to correct the availability dates of these items in Russian OB.
Besides, thanks to Don and Andy to release the tandem HEAT feature, it's been a long time request of mine.
Cheers.
