Like my other thread, post here the armored vehicles of the 20th century that should have never left the drawing board, and give a couple reasons for why it is so horrible
BW choices:
The Panzer MK 2
1. It had a power to weight ratio only 3/5 of the panzer MK 1... why Germany knows how to build engines
2. 20mm gun on a ten ton tank

even the french had 37mm guns in rotating turrets in 1918
3. Less armor than a snowblower, could be knocked out by anti tank rifles and other light infantry weapons
And they built 1000's of these things which would have been obsolete in 1930
The Russian KV-2 150mm tank
1. Loading and firing where unbelievably slow
2. Size and weight put in the repair bay constantly
3. Mobility was at best "questionable"
