Metal , Resin , Plastic , as they say different stokes ..... I'm much more comfortable with plastic as it's easier , IMO , to attach / glue to model . It's much easier to convert / kit bash , and that's important to me as I like to have 4 , 5 , or even 9 of the same tank
. If I add a 5 figure set of tank riders to 3 of my tanks , they all look the same . If I build them myself out of plastic , I can mix and match and kit bash to my hearts content . For example , these guys are kit bashed from the same 3 or 4 bodies from Warlord's plastic Russians
That was my 1st attempt, only 6 , but with a little tweaking , and the odd arm swap - here's how they finished up
With a little bit of thought you can even make groups of figures that can be used on various vehicles . These 2 are atop 85mm ammo boxes and can be put on my T-34/85 or my Su-85 if I so choose
As a modeller I like variety in and on my tanks , it's the same reason I don't like all the molded on stowage Warlord molds on some of their kits , their new LRDG Jeeps for example , very little room to make your's unique . I think a set of Rubicon' Russians will end up in my hands at some point , but they'll probably be assigned to different tanks in my swarm
