How was Fuel Transported Before Jerry Cans?
Before jerry cans were invented, soldiers used a 55-gallon drum filled with fuel. Using these big drums to transfer fuel was difficult and risky to be manually carried because tanks could be vulnerable to enemy attacks. It was challenging to be taken or transported using small aircraft or vehicles. The armies’ machinery needed a more efficient fuel distribution, and it became an urgent need to develop something handier. (Source: Think Defence)
