The M1A2 SEPv4 Abrams will be the new main battle tank of the U.S. military. Recently, footage of an advanced prototype of the M1A2 SEPv4 Abrams tank emerged while the prototype of the Army’s new main battle tank was undergoing testing in the Yuma Testing Grounds in Arizona.
Troops from the 2nd Battalion, 12th Cavalry Regiment, 1st Brigade Combat Team, 1st Cavalry Division were caught on camera testing the new main battle tank. Although the photos from the event were subsequently taken down, several outlets, including the Warzone, managed to see them.
Although the current version of the M1A2 Abrams, the SEPv3, entered service just two years ago in 2020, the U.S. Army is already working with General Dynamics on the new upgrade.

Instead of opting for a new main battle tank—although there are plans for one—the U.S. Army is going with the fourth upgrade to the M1A2 Abrams under the designation of System Enhanced Package 4, or SEPv4.
The M1A2 SEPv4 Abrams will include a more efficient structure, new laser rangefinder technology, ammunition data links, and sensory equipment, including a meteorological sensor that will allow the crew to acquire and engage targets in a variety of weather conditions.
Although the M1A2 SEPv4 will continue to use the same 120mm cannon that current Abrams are using, the new version of the main battle tank will have the ability to fire more advanced 120mm munitions, including the reprogrammable XM1147 Advanced Multi-Purpose (AMP) round.
The Army has stated that it was the M1A2 SEPv4 Abrams will be ready by the middle of the decade and field the first operational drills by 2025.
M1A2 Abrams: A Popular Tank
The U.S. Army’s M1A2 Abrams tank is the most advanced main battle tank in the world. And, as the war in Ukraine is proving beyond doubt, tanks are very much a part of modern warfare.
The war in Ukraine has shown that tank warfare is very much relevant in today’s battlefield. The Russian experience might have highlighted the limitations—or perhaps introduced a new level of criteria for the employment—of tanks. Both sides have used tanks extensively in various roles, including urban warfare, and they depend on them to spearhead their advances.
The M1A2 Abrams, moreover, continues to be a popular weapon system with allies and partners. For example, in August, Poland came to an agreement with the U.S. Department of Defense and General Dynamics for the purchase of 250 M1A2 SEPv3 Abrams main battle tanks for approximately $1.15 billion.
Poland has taken the Russian invasion of Ukraine personally and is the fourth-largest contributor of military aid to Kyiv. Among the billions of dollars that Poland has contributed to the defense of Ukraine are more than 230 T-72 main battle tanks that are spearheading the advances of the Ukrainian military in the south and the east.
The order for the 250 M1A2 SEPv3 was made in large part to replace the gap created by the shipment of the T-72s to Ukraine.
