Oh. My. God. This is a pyromaniac's dream come true: Tanks spewing out a flaming sea of petroleum on a hapless enemy. At least the following infantry are wearing asbestos suits, but what are they going to do when they get to the enemy lines? Roast marshmallows? I recall reading somewhere that when the Germans tried using giant flamethrowers during the First World War their own men were so terrified by the things that they refused to advance.
Hell, I wouldn't be within a mile of one of these track-mounted barbeque lighters, much less walking beside them. One shell in the fuel tank and that's all she wrote.
