Abrams tanks are not suitable for war in Ukraine: what is the reason - Sullivan
In fact, these tanks are not widely used by units because it is not the most useful technique for them in this fight," the adviser said. The Ukrainian military has previously stated that the tanks provided were devoid of some key systems. In particular, the cars came without armor from the depleted uranium, and were also deprived of modern combat modules and communication systems characteristic of standard American versions. Moreover, some of the tanks were repaired before they could be used.
For example, military observer David ex noted that one of the "headaches" tank crews in combat is a feature of engine design. The power plant is equipped with filters, which during the active use of equipment in the conditions of war in Ukraine, are quickly clogged. Therefore, they must be cleaned regularly, otherwise the engine may fail and have to be sent for long repair.
