The M1 Abrams still has a lot of shortcomings and of which, there are weaknesses that cannot be overcome.
Heavy weight requires certain conditions for the M1 Abrams tank’s operations – such as, bridges, roads, ferries or even it cannot function well in soft areas. For example, during the offensive to Iraq, because the country’s facilities were not so developed, the US tank forces struggled to advance, even without too many obstacles from the enemy. In areas where there were no bridges or roads to meet the requirements, this tank would have to wait for the road engineer – very time consuming and vulnerable to attack.
In addition, the large weight is accompanied by a very huge size, making this tank more vulnerable to attack. To put it simply, when at the same distance, the M1 Abrams will be a better target than Russian tanks, simply because they are bigger, easier to hit.
Another fatal weakness that the US can hardly overcome with the M1 Abrams tank, it consumes terrible fuel, which will create a great burden on the logistics force. Although the United States is a master of military logistics, in many cases the fact that armored vehicles, especially main battle tanks consume too much fuel, will significantly reduce combat effectiveness, affecting strategy.
The American M1 Abrams tank has a fuel tank with a capacity of more than 500 Gallons – equivalent to about 1,900 liters. However, it would be no exaggeration to say that M1 Abrams uses gasoline like “water buffalo” by burning nearly 2 Gallons of fuel for every a single mile traveled – equivalent to 7.5 liters of fuel for 1.6 km .
And yet, according to test reports from the US Army, the M1 Abrams tank will cost up to 10 Gallons to start the engine, costing 1 Gallon for every 6 minutes of idling. When traveling off-road, the M1 Abrams tank costs up to 1 Gallon per minute of maneuver – no matter how far it goes.
Such a terrible fuel consumption makes the range of the M1 Abrams quite poor, only about 400 km when traveling on flat roads, and 300 km when traveling cross country.
