A whole tank column on one shelf is what 1:72 military model kits make possible. A tank here is about eight centimetres long, the build takes a few evenings, and a box typically costs around half what a larger size does, so instead of one machine you can field a troop. Subjects cover tanks, half-tracks, armoured cars and lorries from the First World War to the present day. Below: how to choose a subject, and what lifts a small machine well above its size.
1:72 began with aircraft, and armour adopted it because it complements aviation collections and dioramas so neatly. Today it carries the second-broadest offering after 1:35: Soviet T-34s with mine rollers, German half-tracked tractors, modern Leopards. Kits usually run to a few dozen parts, so you see a result quickly and a mistake does not cost you a month.
Simpler kits with accurate outlines can be built with children over a weekend, while detailed boxings with separate return rollers and fine tools on the mudguards need tweezers and patience. Each product listing states the intended builder and the level of work involved.
Alongside 1:72 sits the fractionally smaller 1:76 military model kits. The difference looks trivial until two machines stand side by side on one base, so keep a single scene to a single scale.
Most kits are complete in themselves. If you want more, add a metal barrel, etched grilles or markings for a different unit, all in the matching size.
Every size from 1:350 up to 1:6 is signposted from the military model kits overview.
