But where that name -TANK- come from?
First tank prototipes where designed in the Reinassence Times by Leonardo da Vinci.
Who else?
Guess, soon or later we'll discover the was the first to formulate Coke too!
First operative tanks entered the battlefields in 1917, as a made in britain achivement.
W. Churchill, as minister for the British War Effort, was behind the project. To keep the secret over the new weapon he decided to designate it, in all papers, as Water-Carrier..... so the tank was to figure out as a logistic support to carry water supply to the front line.
Unfortunately the acrominous, W.C. sounded a bit "offensive" for the secret weapon: Water Closh?
The masking name was then changed to Water-Tank! Soon later TANK was the commonly used term for it!
