The first is a pair of 1/87th scale Salvat collectibles repainted for some of the T-55 of the 85th Inf. bgde seen in Beirut.
These ones are CMSC 1/87th scale and sport several camouflages, including the 1973 scheme of brick red/sand/ and green outlined in black.
This pair is Roco 1/87th scale. In the previous and following picture you can see the many details added to these old kits: figure; drum barrels; MMG; antennae; search light and stowage.
And now for the 1/100th models. These two are Skytrex and really nice.
These four are Eko and had the same amount of added details as the ones from Roco in 1/87th scale.
The full group: the 10 of the top rows are for the large battalion (5 companies) of the 58th mechanized bgde; the 6 of the bottom row is for any of the other tank battalions (3 companies).
