British Main Battle Tank Conducting Smokescreen Operations

[@ppatates]

This isn't coal powered there is no steam engine
This is called "smoke screen" making smoke via engine for falling back or supporting infantry

[@SideWinder_999]

someone didn't understand the joke

[@ammartinplays]

It actually uses oil on the exhaust to create the smoke, still can’t take a joke though
