3. This object 490A one may look rather conventional design, but it had one very unconventional feature – it’s rounds charges had to shift its shape before loading (variable form charge).

The #1 was criticized, number 2 was designed up to USSR collapse, only turret built, #3 – 2 tanks were built, only one hull survived to our days.
Maybe some common features like vehicles mentioned in Honeycutt’s – History of the American Main Battle Tank Vol. 2 (Associated Engineers Inc 4-track tank and so on) but not a completely unconventional designs.
Maybe somebody can add some US unusual projects, but I can hardly find something like the above mentioned.
