- The tanks MkI (infantry), MkI (cruiser) and light MkVII are made in negligible amounts. The first two appear to have been removed from production entirely.
- The main types of tanks are the MkIV and MkIVa cruiser tanks (the tanks vary in only small details). The precursor to the MkIV, the MkIII cruiser tank (built in small numbers) differs only in the shape of the turret and potentially has thinner armour.
- The latest tanks are the MkIII infantry tank (built on the basis of the MkII cruiser tank) and the light tank MkVII.
- In British media, the infantry tank MkIIa is called "Matilda" and the infantry tank MkIII is called "Valentine".
- Cruiser tanks MkI and MkII and the infantry tank MkIII are from the same family of tanks.
- Cruiser tanks are from the medium tank weight class, infantry tanks can be medium or heavy depending on their weight."
Commenters from a previous article may note that while the Infantry Tank MkII bears the name "Matilda", the Infantry Tank MkI does not.
