I've got several Zvezda T72 1/100 15mm tanks. I like them mainly because I can get them in every model shop. They are plastic and lent themselves easily for converting. Here you can see some examples of my tanks.
Two Syrian tanks, one with custom era and optics. Two Russian green tanks, one with Qrf T72BV turret. One early type (cast turret) T90 with shtora, in modern Russian camo. Syrian tanks are mostly done. T90 is waiting for AA gun. Green tanks need their AA guns and some paint.
