The marking 1:56 is simply the ratio notation for the 28 mm wargaming height, so the same regiments appear under both labels and the two are fully interchangeable on a table. Rule sets written for this size assume units of several dozen men, which is why the infantry for it is boxed by the platoon rather than sold as single castings. Plastic multipart sprues with interchangeable heads, arms and weapons are the norm here. Since the two labels mean one size, anything bought as 28 mm drops straight into a 1:56 unit: the infantry is catalogued by millimetre height in 28 mm wargaming figures, and the vehicles that go alongside it in 1:56 military vehicle kits.
