British Major General Percy Hobart served during WWII and was tasked by Lord Alanbrooke (the British version of George Marshall) and Winston Churchill with designing tank modifications that could overcome various obstacles/ impediments/ problems in the D-Day landings. The results were interesting, bizarre and sometimes effective. Indeed, some were then used by teh US, and others, not used by the US, resulted in criticism, when they arguably could have saved soldier's lives.
The whole group of whacky designs became collectively known as "Hobart's Funnies".
