1:56th Scale (28mm) T62 Main Battle Tank From Sloppy Jalopy

In terms of scale we chose both! For our inter-war, WW1 and VBCW range we decided to do 1/48th as the figure ranges tend to be 'larger' 28mm. For the Cold War range we went with 1/56th as the existing ranges at the time, particularly the much-lamented Mongrel Miniatures were slightly smaller and seemed to fit better with what was then the new concept of 1/56th scaling.

FWIW bases also tend to lift figures a bit and make them look taller / bigger than they are, and for my personal stuff I tend to base my vehicles to make them match and 'look right' But a lot is down to personal taste…
