{{main|Tanks in World War I}}

In World War I, the first tank, the {{convert|28|LT|t ST|0|adj=on}} British [[Mark I tank|Mark I]], was designed for supporting infantry by crossing trenches and attacking machine-gun posts. This became known as a heavy tank alongside other, lighter, types.

A lighter British tank introduced into service in 1918, at {{convert|14|LT|t ST|1}} and armed with machine guns only was given the designation [[Medium Mark A Whippet|"Tank, Medium Mark A"]] and known as the "Whippet".

The two-man {{convert|7|t|LT ST|0|adj=on}} French [[Renault FT]] was known as a light tank.

[[Super-heavy tank|Super-heavy]] breakthrough tanks such as the [[Char 2C]] ({{convert|69|t|LT ST|0|abbr=on|disp=or}}) or the [[K Panzerkampfwagen|''K-Wagen'']] ({{convert|120|t|LT ST|0|abbr=on|disp=or}}) were nearly completed before the war ended. In comparison, the current British MBT, the [[Challenger 2]], weighs some {{convert|60|t|LT ST|0|abbr=on}}.
