Ukrainian brigade's modified M1A1 Abrams tanks pose logistical tests

The 47th Independent Mechanized Brigade is one of Ukraine's finest units, predominantly outfitted with American equipment. In addition to the well-known M2A2 Bradley infantry fighting vehicles, they also utilize M1A1 Abrams tanks with extra reinforcement.

Ukrainian forces are currently engaged in intense battles west of Avdiivka, where the 47th Independent Mechanized Brigade and other nearby units are determined to hold their positions at all costs. The video below shows a heavily modified M1A1 Abrams tank firing at Russian positions.

Ukrainians have mixed feelings about the American tanks. On the one hand, they appreciate their firepower and fire control system and the isolation of the ammunition from the crew. However, they criticize the armour for not providing sufficient protection against drones.

To address this, Ukrainians have begun adding Kontakt-1 reactive armour blocks to certain sections of tanks. In the video above, it appears this tank is equipped with a reactive armour kit from two T-72 tanks. Numerous blocks tightly cover the tank's silhouette from every side.

This type of armour will be effective against FPV or Lancet-3 drones, but it significantly increases the tank's already considerable weight. A standard M1A1 SA Abrams weighs nearly 70 tonnes, and such an extensive package of Kontakt-1 reactive armour adds over 2,000 kilograms (armour for one T-72 weighs 1,200 kilograms). Each block weighs about 6 kilograms, in addition to the weight of the mounting framework.

The downside of this reinforcement will be significantly faster wear on the suspension or engine, leading to more frequent breakdowns. Ukrainians have already raised concerns about this issue with the Abrams tanks. Furthermore, the question remains whether the additional armour obstructs the covers of the ammunition storage, potentially redirecting the force of an ammunition explosion outward.
