Heat, fumes and no plumbing inside the Mark IV

Easily the most unpleasant tank to crew! #thetankmuseum #militaryhistory #famthetankman
The engine wasn't tucked away from the crew. It sat in the middle of the tank, heating the air that everyone inside had to breathe.
That design detail anchors The Tank Museum's fast-starting Short about the British Mark IV. Rather than concentrating on armor or firepower, it explains what occupying the machine meant for the people operating it: extreme heat, exhaust fumes and nowhere resembling a bathroom.
The narrator describes interior temperatures reaching 50°C. Carbon monoxide from the engine and cordite fumes from firing weapons added to the ordeal. Empty artillery shell casings served as makeshift toilets, while motion and poisoning could leave crew members vomiting. All of this happened while the tank was under enemy fire.
The museum calls the Mark IV "one of the most unpleasant tanks to crew in history." The explanation is less about a single design flaw than several hardships sharing the same enclosed space.
The Short is running far ahead of the museum's usual start, and its comment section has already attracted more than ten times the comments of a typical full first day. Much of the discussion centers on the heat comparison, with viewers invoking summers in Australia and the southern United States. The engine placement gives that comparison its essential context: this wasn't simply a hot day outdoors.
