Thanks to the 14.6-ton weight of the T-14 tank, it can accommodate five crew members while carrying 2800 machine gun bullets, 42 shells and some supplies, as well as enough fuel to travel over 400 kilometers.
Of course, the personal weapons of the five crew members are also included. These are to be used for self-defense and combat when the tank is scrapped or breaks down.
The T-14 tank also has a significant improvement in speed. Although it has also gained much in weight, the T-14 tank can still maintain an average speed of at least 26 kilometers per hour on flat ground, with a maximum speed of around 30 kilometers per hour.
But data taken only on flat surfaces can't illustrate much, since tanks are designed to adapt to various road conditions, even against trenches and gullies dug by the enemy.
Unfortunately, even with enhanced power, the T-14 tank is not fast on non-flat terrain.
