Interestingly, the first tank attack launched by the British Army during the Battle of the Somme in 1916 involved 49 Mark I tanks. Only 32 reached their initial positions (17 tanks were disabled due to breakdowns), and of the 32 that launched the attack, 5 got stuck in the mud and 9 failed for technical reasons. Nevertheless, even the remaining 18 tanks were able to advance 5 km behind enemy defences, with British losses in this offensive being 20 times less than usual.

At that time, tanks were produced in two main modifications - the "female" (only with machine guns) and the "male" (machine guns and two 57 mm guns).

The word "tank" is derived from the English word "tank" (i.e. "tank" or "cistern"). The origin of the name is related to the purpose of disinformation of enemy agents who were monitoring the transport of troops and weapons by rail. When the first tanks were being sent to the front, British counterintelligence spread rumours that the tsarist government had ordered a batch of fuel tanks from England.

In Russia, the tank was initially called the Lokhan.
