The Syrian Scud B were also placed in Lebanon, but kept as a strategic reserve. These models are QRF.
Same with the Frog 7, both role and brand.
The BM-21 are QRF and uncamouflaged as some photos I saw.
These are Made In China trucks transformed into BM-21. They are roughly 1/90th scale and fit nicely with the previous QRF´s.
The main changes were new resin wheels (from 1/43 cars) and Evergreen rocket tubes, alongated sides and side exaust tubing.
These are refuelling trucks of unknown origin, with a new paint job inspired on recent photos of these kind of trucks.
T-34 122mm SP are conversions from the Kopro T-34 in 1/87th scale. The 122mm had to be scratchbuilt and some rectangular boxes and other details were made in Evergreen. The figures are 15mm Peter Pig Syrians.
The BRDM-2 AT-5 Spandrel are Skytrex.
The 2S1 Gvozdika and 2S3 Akatsyia are also QRF. The latest were not in Lebanon in 1982 but are nice models.
