Longer, Thinner, Heavier
The AMX M4 project remained still for almost all of 1946. This is directly connected with the ARL 44 entering trials in March of that year. The first French post-war tank was late for almost a year, and trials showed that the vehicle needs extensive improvements. These trials couldn't have left the new tank unaffected. Sadly, the details of the trials are still unknown, but judging by the upcoming metamorphosis, the vehicle's stability was questioned.
