A softer-running lower hull is what 1:72 tank tracks give small armour. The range includes combined track and wheel sets for the BMP-1 in early and late form, the BT-7 fast tank in both patterns, the Polish 7TP, the M24 Chaffee, the amphibious LVT, the Pz.38(t) and the small Pz.I and late Pz.II.
1:72 only tolerates fine links, which is precisely why replacement runs pay off here: guide horns and lightening holes come out better resolved than on the thin loops in the box. Glue in short sections, because small links set fast. Choose the vehicle from 1:72 military vehicle kits, compare sizes under model tank tracks, and shoe wheeled subjects of the same size with 1:72 wheel sets.
