I'm often embarrassed by my lack of knowledge on armor, so it was nice to run across this YouTube channel that cuts through all the bullshit and myths surrounding WWII tanks. The man behind this started out as a trooper in the Irish Defense Forces driving a Chieftain tank, then emigrated to the US, joined the National Guard, got a commission and ended up commanding a US tank platoon in tours of Iraq and Afghanistan. In effect, he's been both the the filthy enlisted man crawling through the bowels of a tank with a wrench, and the guy in charge with knowledge of tactics and strategy. Well-rounded as they say. You can find him on YouTube as "The Chieftain." A handle he picked up as a nod to both his Irish roots, and the beloved Chieftain tank he started on. He crawls through old tanks pointing out odd engineering quirks that would never occur to anyone that never had to live or work on one of the damned things. In the vid series below he makes the case that that the Panther wasn't as much over-engineered (the standard line), as badly laid out. For example, if you can't get at the transmission to do routine maintenance without pulling out everything in the interior of the tank, you probably won't do the routine maintenance, and thus your transmission is liable to fail much earlier than would otherwise be the case. In this one he looks (rather favorably) at the Sherman. In addition to thorough reviews of tank types, he has a number of lectures on the background of WWII tanks - the political infighting, logistics, manufacturing and so on. This YouTube channel is a gold mine of information and anyone interested in WWII tanks would do well to subscribe.
